For your convenience, each question is curbn up followed by the allot answer and an rendering of the correct response. Work your counselling consistently by these, comparing It with your consume answer. rase If you chose the correct alternate, you whitethorn find that the explanations we give argon useful. Try to understand the explanations. some of the Items measure Insight, non Just factual copeledge. You impart non pass this curriculum if you try and memories the questions and answers heading 1 The coating of quantitative look for in psychology is best described as aiming to 1 . Polo appropriate statistical rills which heap be utilise to determine the human relationships among psychological changeables that blow over at a level greater than chance 2. Develop theories that helps us to apologize human experience and behavior 3. makeulate clear hypotheses found on insights most human experience and behavior 4. alter theoretical constructs into measura ble varying stars through personalization upshot alternative 2 gives the correct answer. The intent of research Is to develop theories which faecal matter rationalize surveys of human behavior and experience. plectrons 3 and 4 refer to stages In the process of doing maiden research only if these are non the goals of the research. The goal of the research Is also not to develop statistical running plays, as Implied In woof 1 . These examines are genuine by statisticians and are used by research imparters in hearty and early(a) scientific research, al unmatched developing the examinations is not interrupt of the goal of the research. PECCARY/201 5 head playscript 2 A psychologist believes that personality factors much(pre titulary) as ability to get on with other the great unwashed in a team are likely to affirm on work out their success in a team sport.To investigate this, she draws a sample of participants in competitive sport, comprising f soccer players, hockey players and cricketers from various sports clubs. later evaluating their death penalty on an appropriate psychometric test, she delves players from the three categories of sports Into devil groups those who shake life-threatening social skills and those who tend avoid social contact. She then uses evaluation forms, ground on interviews with different sports experts, to assess the actual sports surgery of the members of the sample.The subject variable in the reflect is and the independent variable is 1. Measured sports exercise social skills 2. Type of sports social skills . kindly skills measurable sports exercise 4. Social skills oddball of sports Answer Option 1 is correct. The researcher wants to determine whether sports performance (a touchstone of how tumefy a particular sports participant performs) depends on social skills. This Implies that the construct social skills Is the autonomous variable which Is varied to see how it affects the depen dent variable, the measurement of sports performance. The population from which the sample was displace (the types of sports participants that were conglomerate), but in the context of this scenario this variable is not existence investigated here. It would be affirmable to compare the three groups but this would not answer the research question. doubtfulness 3 dish out the following financial account That flesh of pause during which brain rhythms resemble those of an alive(p) person is called paradoxical sleep or rapid eye dejection (ERM) sleep. This statement is a 1. Conclusion establish on verifiable research 2. Operational interpretation 3. Search possible action 4. Inference based on watching Answer Option 2 is correct. The statement gives a translation of ERM sleep in terms of the measurement of brain waves (which burn be do with an EGG machine). Since it is simply a statement about what the expression paradoxical sleep or rapid eye movement (ERM) sleep m eans, it is not a conclusion, hypothesis or inference, as suggested by the other picks. 6 headways 4 to 6 are based on the following research scenario. A psychologist wants to convey how aspects of motivation wad influence states productivity in their work.She reads an article which claims that an key aspect of motivation is locale of conquer, which distinguishes quite a little who are driven by their own personal ambition from those who act by conforming to a social group. To test this idea, draws a sample of 100 workers from a number of companies in the information applied science sector. She divides the workers into two groups, those with an internal locus of simpleness and those with an external locus of falsify, based on an appropriate psychometric test. She then uses chore evaluation forms to assess the actual work performance of the workers in the two groups.Question 4 Which of the following gives the best expression of the hypothesis that the researcher wishes t o test? 1 . pauperization affects the productivity of workers. 2. Internal locus of direct is related to high productivity. . The frolic performance of workers is influenced by locus of control. 4. Motivation of workers is influenced by locus of control. Answer Option 3 is correct. Option 3 is the clearest expression of an appropriate research hypothesis. Option 1 is as well as vague motivation is probably too multiform to be captured in a undivided construct.Option 2 is too specific it is not clear from the information given up in the scenario whether internal or external locus of control stinker be judge to lead to higher(prenominal) productivity. Locus of control is regarded as an aspect of motivation (according to the scenario), not as a separate construct (or variable) that can be compared to it, so option 4 is also wrong. Question 5 given up that research is an investigation of a relationship surrounded by (two or more) constructs, which of the following constructs throw to be compared to do this (b) motivation (c) locus of control (d) employment evaluation forms (e) people who work in the information applied science sector 1. A) and (c) 2. (a), (b) and (e) 3. (a), (c) and (e) 4. (c) and (d) Answer The correct alternative is option 1 . Locus of control is the specific aspect of motivation that is being studied, which excludes option 2. In this particular context, people who work in the information technology sector is part of the comment of the population that the researcher chooses to study, not a construct that is being compared to another, so option 3 is preposterous. Option 4 is incorrect because product line evaluation forms are the instruments used to measure the construct Job performance, and not a construct as such. Question 6 The dependent variable in the study is and the independent variable is 1 . Job performance locus of control 2. Locus of control motivation 3. Job performance productivity . Locus of control Job perfo rmance The dependent variable is the one that is predicted or explained, and the independent variable is manipulated to see how it affects the dependent variable. In this study the researcher tries to predict Job performance with the aid of locus of control. In other words, the researcher is trying to see if Job performance depends, to a significant degree, on locus of control.Option 2 is wrong because locus of control is the aspect of motivation that is being studied. In a similar counseling, Job performance is equivalent to productivity, which excludes option 3. Question 7 In scientific research, the word theory refers to a(n) 1. Reasonable guess or creative insight which seems to explain a phenomenon 2. Method to make the constructs which are involved in a phenomenon visible through a process of personalization 3. Investigation or procedure which is performed to determine the relationships among variables 4. Explanation of wherefore the observations that were do are as th ey are, or are related in the way that they are related Answer Option 4 is correct. As explained on foliate 4 in the Guide for PECCARY, a theory is a framework for facts it s the explanation of why the facts (I. E. Observations, measurements) are as they are, or are related in the way in which they are related, based on empirical investigations. Option 1 is a description off hypothesis, but this is often how the word theory is option 3 is a description of a process such as an examine by which a theory can be evaluated but not to a theory as such.Question 8 Consider the following statement The experience of sozzled emotion is accompanied by physiologic reactions such as an increase in heart rate. This statement can be viewed as a research hypothesis because it a) makes a prediction that can be tested by observation (b) describes a possible relationship between variables 1. (a) but not (b) 2. Both (a) and (b) 3. (b) but not (a) 4. Neither (a) nor (b) 8 A psychological hypothesis canontes a testable empirical claim, that is, a prediction which can in principle be observed, and this usually involves postulating a relationship between two or more variables.Question 9 A psychologist uses a psychometric test to study the intuition of school children. Intelligence is the variable and the psychometric test represents the variable in this study. 1. unaffiliated dependent manifest operational 3. drug-addicted independent 4. Latent manifest A hidden or underlying ( possible) aspect of a construct has to be made visible (manifest) to be observed. Intelligence is a latent variable because it cannot be observed directly. The results of the psychometric test can however be observed directly and can so be regarded as the manifest variable.Note that the test result is the measurement by which lore is made visible, so these are manifestations of the equivalent construct (or variable), only in one form it is observable (manifest) and the other form it is hidden ( latent). Dependent and independent refer to relationships between two different variables, so options 1 and 3 are both incorrect. The psychometric test is the operation by which the variable intelligence is measured (or personalities), but you would not refer to the test or test result as an operational variable, so option 2 is also not correct.Question 10 An industrial psychologist wants to investigate the levels of assertiveness among different categories of workers in a large company. He draws a sample of 200 workers and then divides them into managers, clerical workers, technical workers and manual errors with the intention of get each participant to do a test to determine their level of assertiveness. The discussion section of workers into these four groups represents a measurement on a level. 1. Nominal 3. Interval 4. Asia When numbers pool are used to allocate people or objects to categories or groups with no importation of intensity or ordering related to the size of t he number, it is referred to as a nominal level or nominal plateful of measurement. Note that while one may presume that managers have a higher post than the rest and perhaps manual workers can be said to have a low rank, there is no obvious way to decide whether lyric workers have a lesser rank than technical workers or the other way round, as it would depend on the specific types of work that they do.A senior clerk can outrank a Junior technician, and ill-doing versa. (Nominal and other scales are explained in accompaniment B of the Guide). PECCARY/201 9 Question 11 If a pupil will be chosen to go on a field trip from a class of 13 girls and 17 boys, what is the chance that Joanne (one of the 13 girls) will be chosen, given that a girl will be selected? 1. 1/13 2. 14/30 3. 1/30 4. 1/17 You have to use the basic formula for probability We know that there are 13 possible outcomes (any one of the 13 girls can be selected) and we also know that there is only one favorable govern ment issue Anyone being selected).
