a two-independent-sample t test & a one-way between-subjects ANOVA

A T&D researcher measures differences in recall between male and female participants following a training session. If different participants were in each group, then what type of statistical design might be appropriate (i.e., "would work") for this study?

a one-way between-subjects ANOVA

A hospital records depression scores for 12 nurses in each of 4 specialties (emergency, pediatrics, etc.). If depression scores for each of the 48 nurses are recorded in each specialty, then what type of statistical design is most appropriate for this study?

a one-way between-subjects ANOVA

A professor compared differences in class grades between students in their freshman, sophomore, junior, and senior years of college. If different participants were in each group, then what type of statistical design is appropriate for this study

(3, 84)

A researcher conducts a study in which k = 4 and n = 22 in each group. What are the degrees of freedom for the one-way between-subjects ANOVA?

4

A researcher conducts a study of 5 groups where N = 80. What are the degrees of freedom between-groups for the one-way between-subjects ANOVA?

The degrees of freedom between-groups are the same in each study.

A researcher conducts two studies. In Study 1, she recorded the amount consumed (in calories) among 8 participants observed at 3 meal times (breakfast, lunch, and dinner). In Study 2, she conducted the same study, except that n = 12 participants observed at each of 3 meal times. Which study is associated with a larger value for degrees of freedom between-groups for a one-way within-subjects ANOVA?

analysis of variance

ANOVA stands for ________.

a one-way between-subjects ANOVA

An HR manager, in conducting research on employee productivity, divides participants into groups that will engage in low, moderate, or intense levels of effort. The total time taken by participants to complete their tasks are then recorded. What type of statistical design is appropriate for this study?

different participants are observed one time in each of two or more groups for one factor

Computing a one-way between-subjects ANOVA is appropriate when ________.

the number of factors in the design

For an analysis of variance, the term "one-way" refers to _________.

the degrees of freedom in the numerator & the degrees of freedom between-groups

In an ANOVA, the degrees of freedom for the between-groups variability is ________.

degrees of freedom error degrees of freedom denominator degrees of freedom within-groups

The degrees of freedom for error is called ________.

observing different participants one time in each group

The term "between-subjects" refers to _________.

observing the same participants in each group

The term "within-subjects" refers to ________.

larger

Without changing the value of error variance, the ________ the between-groups variability, the more likely we are to reject the null hypothesis.
