APPROVED NEW MODIFIED 2026 LATEST
A researcher wants to examine the relationship between post-
partum depression and maternal age. She recruits 50 women
who have given birth within the last 3 months from the WIC
(Women, Infants, & Children Food and Nutrition) office. She
collects demographic information from each woman
(including age, race/ethnicity, and educational achievement)
as well as administering a post-partum depression survey.
Which of the following statistical tests should she select for
her analysis? --CORRECT ANSWER--Pearson's correlation
coefficient (r)
A group of researchers studied functional impairment scores
in a group of 10 patients before and after a new rehabilitation
intervention. The researchers set the alpha at 0.05 which
meant that the critical t value would be 2.26 (9 df). Data
analysis showed t(9)=2.84, p=.045. What do these results
mean? --CORRECT ANSWER--There was a statistically

, significant difference between the functional impairment
scores obtained before and after the intervention.
In a study, a researcher finds that as A increases, B also
increases. The analysis shows that the strength of the
relationship is 0.78. What type of linear relationship is this? --
CORRECT ANSWER--positive
In a research study on number of hours parents spent at
children's sporting events and number of incarcerations that
the offspring experienced by age 30, the calculated Pearson's r
was -.95. What does this Pearson's value signify? --
CORRECT ANSWER--As the hours of parents spent at
children's sporting events increased, the number of
incarcerations that the offspring experienced by age 30
declined
Which of the following correlation coefficients shows the
strongest relationship? --CORRECT ANSWER---.85
