## very Important research aptitude

 Question 1
Two researchers were studying the relationship between amount of sleep each night and calories burned on an exercise bike for 42 men and women. They were interested if people who slept more had more energy to use during their exercise session. They obtained a correlation of .28, which has a two-tailed probability of .08. Alpha was .10.            What conclusions should you draw regarding the null hypothesis?
 A Reject B Accept C Cannot determine without more information D None of above
 Question 2
What conclusions should you draw regarding this study?
 A The correlation was significant B The correlation was not significant C A small relationship exists D No relationship exists
 Question 3
What is the correct statistical null hypothesis?
 A There is no correlation between sleep and energy expanded B Rho equals zero C R equals zero D Rho equals $r$
 Question 4
What is the correct term for the variable amount of sleep?
 A Dependent B Independent C Predictor D $y$

People who are available, volunteer, or can be easily recruited are used in the sampling method called ........
 A Simple random sampling B Cluster sampling C Systematic sampling D Convenience sampling
 Question 6
Which of the following types of sampling involves the researcher determining the appropriate sample sizes for the groups identified as important, and then taking convenience samples from those groups?
 A Proportional stratified sampling B Quota sampling C One-stage cluster sampling D Two-stage cluster sampling
 Question 7
A type of sampling used in qualitative research that involves selecting cases that disconfirm the researcher's expectations and generalizations is referred to as ........
