What is the r value for perfect negative correlation?
A. R = 1
B. R = 0
C. R = -1
D. R = -0.5
What happens to the confidence interval as sample size increases?
A. Doubles
B. Stays the same
C. Gets bigger
D. Gets narrower
What happens to the confidence interval as sample size increases?
A. Doubles
B. Stays the same
C. Gets bigger
D. Gets narrower
If the sample size increases, the 95% confidence range stays the same;
however the 95% confidence interval gets narrow since the standard error decreases if the sample size is larger
What study type should be used if you wanted to investigate if a rare exposure is associated with a disease?
A. Cohort study
B. Case control study
C. Clinical trial
D. Cross-sectional survey
What study type should be used if you wanted to investigate if a rare exposure is associated with a disease?
A. Cohort study
B. Case control study
C. Clinical trial
D. Cross-sectional survey
If an exposure is rare there may be too few people exposed in a case-control study to be able to draw conclusions
