31. A correlation of (.10) is a strong correlation FALSE TRUE 32. Another characteristic of the experimental method is that it tries to eliminate all possible confounding variables TRUE FALSE Randomization ensures that the extraneous variable affect one variable but not the others 33. Which of the following sentence is most correct? a. Randomization ensures that the extraneous variable is just as likely to affect one experimental group as the other All of the above None of the above b. c. d. 34. All of the following belong in Participant variables EXCEPT for a. Age b. Gender c. Answers on the EIPQ d. Marital status 35. A reliable measure will yield the same (or very similar) result every time it is measured. TRUE FALSE 36. Which of the following sentences is most correct? Test-Retest Reliability is assessed by measuring the same individuals at two points in time a. b. Test-Retest Reliability is assessed by measuring multiple individuals at two points c. Test-Retest Reliability is assessed by measuring the same individuals at one point d. None of the above in time in time 37. Which of the following sentences is most correct? a. Cronbach's alpha correlates each item of the test with 1/3 of items b. Cronbach's alpha correlates each item of the test with every other item c. Inter-rater Reliability refers to the correlation between the observations of one rater d. None of the above

Explanation / Answer

1.False

Correlation coefficients range from -1to 1, with -1 showing very strong negative correlation, 1 is very strong positive correlation.0 means no correlation. A correlation of .10 means that correlation is present in the positive direction but is very weak as it nears zero.

2.True

confounds are variables that the researcher fails to control, but still an experiment involves manipulating one variable while keeping all other external variablea constant to see effrct on second variable.

3.B)

randomization ensures that external variables is as likely to affect one group as other.When subjects are randomly assigned a group, it ensures that the effect of extraneous variables like for example participant variables gets evenly distributed between the two group making them similar, except for the difference that the researcher manipulates.

4. C)

participant variables are extraneous variables that include a person's individual characteristics like age, sex, personality traits etc, that may effect the participant's performance in a test.his actual performance can be a dependent variable depending on the research condition.

5.True

Reliability of a measure includes temporal consistency, which can be meadured as tedt retest reliability.

6. A)

Test retest is the measure of reliability to establish that the test when given to the same person under similar conditions will produce similar results.

7.B)

Cronbach’s alpha is a measure of internal consistency by measuring the average covariance among items on a scale.
