Exam 12: Exploring Statistics Comparing Differences in Health Care

The results of a new physical therapy treatment for improving rehabilitation post knee surgery resulted in an effect size of .07. This demonstrates which type of effect size?

If a significant F ratio is revealed in a Repeated Measures ANOVA, which test should be used to determine what differences have occurred between the participants' measurements?

MANOVA is a variant of the Student's t-Test that allows for the study of multiple dependent variables.

When comparing groups in a study, which question is not essential for clinicians to answer?

When using Hotelling's T² , the effect size is determined by calculating Cohen's d statistic.

Which test statistic is an extension of t-Test that involves more than two groups?

The F value in a MANOVA is ______________.

Hotelling's T squared can be used when only one variable is compared between two groups.

One way to assess the magnitude of the difference between groups is to calculate an affect size.

Will an affect size be calculated when the group's mean are equivalent under the null hypothesis?

Which factor can increase the complexity of interpreting the statistical analysis?

With a Repeated Measures ANOVA, which statistic is used to check for sphericity and protect against a type I error?

Which of the following procedures partitions the variability into three distinct parts on the ANOVA table?

What is examined if there is a significant interaction found using factorial ANOVA?

In which of the following is statistical significance more likely to be found?

When using a t-test, what is the suggested minimum number of individuals per group?

Which of the following is an observed test statistic?

Statistical significance and clinical significance can be used interchangeably when discussing research.

The paired t-test is considered more powerful than the independent samples t-test because there is less variability created.

Which of the following tests should be used to compare two independent groups using one categorical independent variable and one continuous dependent variable.
