Question 1 (1 point) Listen a What is the difference between a research question and a research hypothesis? 12 Usually research questions are more vague than hypotheses None of the other choices Usually research questions are exactly the same as research hypotheses Usually research questions are more precise than hypotheses Question 2 (1 point) Listen What are the benefits of knowing about the previous research in a particular field of interest? We can see how others have tackled similar research problems We can see what other researchers have suggested needs following up in future research All of the other answers It saves us undertaking research that may be pointless Question 3 (1 point) ) Listen According to the description of the research process in this chapter, how do we decide whether there is support for a particular research hypothesis? We design a study and then collect and analyze our data in such a way as to test our hypothesis We rely on previous research to test a new research hypothesis We need to interview other researchers to see if they agree with our hypothesis We see if the research hypothesis makes logical sense Question 4 (1 point) Listen Which of the following constitute the main focus of interest for us when conducting quantitative research? Publishing our research The questionnaires that we use Variables Participants' demographic details Question 5 (1 point)Question 5 (1 point) ()Listen a Which of the following could be considered as a ratio level variable? 11 12 Ratings on a five-point scale for satisfaction with out-patient services Time taken to complete a program of physiotherapy None of the other answers Occupation of participants Question 6 (1 point) = Listen Why is it that temperature scales cannot be classes as ratio level variables? They do not have a fixed/absolute zero They are too complicated There are too many scales for consistent measurements They contain arbitrary intervals between adjacent values on the scales Question 7 (1 point) )Listen In the scheme outlined in this chapter, which of the following represents the correct ordering of the levels of measurements? Nominal, ordinal, interval, ratio Interval, nominal, ordinal, ratio Ordinal, ratio, interval, nominal Ratio, ordinal, interval, nominal Question 8 (1 point) Listen What is the defining characteristic of interval level data? You can put the categories you have in order of magnitude You have a fixed zero You have equal intervals between adjacent points on the scale You have categories which cannot be ordered in a meaningful way Question 9 (1 point) Listen Correlational designs tell us about:2:01:20 elapsed X Question 13 (1 point) 6 ) Listen In which of the following designs are you least likely to have a problem with 12 confounding variables? Both experimental and correlational designs Correlational designs Experimental designs Quasi-experimental designs Question 14 (1 point) ) Listen Which of the following designs are best for establishing causal links between variables? Correlational designs Experimental designs Both experimental and correlational designs Quasi-experimental designs Question 15 (1 point) Listen after an operation OQuestion 15 (1 point) Listen UT a 10 11 12 O O No. of painkillers taken after an operation O O O O O O O O 10 20 30 Minutes spent by surgeon with patients prior Based on the scattergram, what can you conclude about the relationship between the two variables? That there is a negative relationship between minutes spent with patients and painkillers taken That there is a positive relationship between minutes spent with patients and painkillers taken No conclusions can be drawn from this scattergram That there is no relationship between the two variables
