Question

A primary disadvantage of a longitudinal design is

		the amount of time it takes to conduct the study
		that cohort/generation effects are likely to be present
		that confounding variables cannot be controlled as well as in cross-sectional designs
		they are nearly impossible to conduct due to attrition

A relationship between variables characterized by an increase in one variable that occurs with an increase in the other variable is called

		a positive relationship
		a negative relationship
		a causal relationship
		a predictive relationship

A quasi-experiment was conducted to compare men’s and women’s attitudes about extramarital affairs. Men and women who are married were recruited to complete a survey about their attitudes. The researchers then compared scores on the survey for men and women. The appropriate statistical test to analyze the data in this study is

		one-sample t-test
		an independent samples t-test
		a paired/related samples t-test
		an ANOVA

Answer 1

Answer)

There are three types of relationships

1)

When both the variables move in the same direction = positive

When variables move in opposite direction = negative

Third is no relationship

As here both varibles are increasing

Answer is positive relationship

2)

As here we have two independent samples of men and women respectively

We will use independent samples t test
