You are interested in gender differences in study skills among
college students. For your study, you asked students to complete a
multi-item standardized scale on study skills.You want to determine
if there is a difference in study skills by gender (male vs.
female). Which statistical test would you use to determine if there
is a difference between males and females?
Independent t-test
Dependent t-test
Simple ANOVA
Chi square

A group of researchers want to determine if there are any
significant differences in marital satisfaction between male and
female spouses. To test this hypothesis, they collected data on
marital satisfaction from 28 couples (i.e., 28 men and 28 women).
They observed that the average marital satisfaction among men was
6.5, and the average among women was 6.0. The sum of squares for
the difference scores (SSD) was 440. Additionally, male and female
spouse marital satisfaction were strongly related (r...

. The following data represent the final exam scores of 18 male
students and 18
female students.
Male: 68, 68, 72, 73, 65, 74, 73, 72, 68, 65, 73, 66, 71, 68,
74, 66, 71, 65

58, 60, 73, 58
Is there any significant difference between the average exam
scores of male and
female students? Explain your answer.

Q1. In a study of binge drinking among undergraduates at Ohio
University, a researcher was interested in gender differences as
related to binge drinking and to drinking-related arrests. She
wanted to know two things: (a) Is there a significant relationship
between gender and binge drinking (as defined by 5 or more drinks
at one sitting), and (b) Is there a significant relationship
between gender and drinking-related arrests? A random sample of
males and females were asked about their experiences with...

Experimental Study Design
Suppose that you have been hired by the university
administration to design a randomized experimental study to assess
the following hypothesis among undergraduate students:
Attending weekly yoga classes leads to better performance on
exams.
Be sure that your study design addresses the following
elements:
Refine the study hypothesis so that it is as specific as
possible and contains all elements of a “good” hypothesis. Remember
that the design, conduct, and analysis of the study flows from the...
