Exam 19: Selection of Appropriate Statistical Methods: Integration of Design and Analysis

Match the example with the appropriate statistic: -A two variable associational question, both variables normally distributed.

Tiger Woods hypothesizes that Master's Champion winners will score better than non- Master's Champion winners on the golf tour based on their average score for the year. This hypothesis should be tested with what statistic?

Associational statistics should be used when there are seven unordered levels of the IV.

What statistic would you use for a 3 X 3 X 2 factorial design with a normally distributed DV?

Match the example with the appropriate statistic: -Ordinal DV, one IV with 3 or more levels, between-groups design.

Match the example with the appropriate statistic: -Several normal DVs considered together, two or more IVs, between-groups design.

Jennifer Lopez wants to compare audience reactions to three of her movies (Selena, Anaconda, Out of Sight) using a summated Likert scale assessment tool. What type of statistic is appropriate for her to use?

What statistics should be conducted with two variables that are nominal?

A factorial design has only one IV and one DV.

When there is a negative association between two variables, participants who have low scores on variable one tend to have high scores on variable two.

Experimental, quasi-experimental, and comparative approaches utilize the same types of statistics.

Match the example with the appropriate statistic: -Several normally distributed IVs, one normally distributed DV.

Lucky Larry is going to match pairs of lotto winners and non-lotto winners on age and gender. He will then measure them on the dependent variable "quality of life" as assessed by their annual income. What statistic would be best?

Match the example with the appropriate statistic: -Within-subjects design, one normally distributed DV, two IVs.

Match the example with the appropriate statistic: -One IV with 2 levels, normal DV, between-groups design.

Using Figure 19.3 In the text , what type of independent variable is needed to conduct a one-way ANOVA? What type of dependent variable is needed?

Difference statistics are used to compare a few groups in terms of each groups' average scores on the DV.

Dr. Spielberg wants to assess excitement at the Golden Globe Awards and the Academy Awards. He invites 30 movie stars to attend both functions and asks them to rank the awards in order of preference (1 = most preferred/30 = least preferred). What statistic should he use?

What are the three general assumptions for the use of parametric statistics?

Every statistical test is based on certain assumptions. Some of the assumptions for parametric difference statistics include:
