1. For the following scores, find the mean, median, and the mode. Which would be the most appropriate measure for this data set?

Week Seven Homework Exercise Answer the following questions, covering material from Ch. 13 of Methods in Behavioral Research Define inferential statistics and how researchers use inferential statistics to draw conclusions from sample data. According to Cozby (2009) inferential statistics are used to determine whether we can in fact make statements that the results reflect what would happen if we were to conduct the experiment again and again with multiple samples Define probability and discuss how it relates to the concept of statistical significance. Probability is the possible that an outcome of an experience or an event will occur (Cozby 2009) Statistical significant and probability are one in the same. A researcher is studying the

4. Calculate the following measures of central tendency for the set of cube measurement data. Show your work or explain your procedure for each.

6. Based on questions 3, 4, and 5 is the mean or median a better estimate for the parameter of interest? Explain your reasoning.

Some questions in Part A require that you access data from Statistics for People Who (Think They) Hate Statistics. This data is available on the student website under the Student Test Resources link.

Refer as needed to the material in Chapters 12 and 13 of the textbook. Keep the following tips in mind as you research data, as well as organize, analyze, interpret, and illustrate these data:

Let’s use what you learned not only earlier in the class but also information from Module 7 for this assignment. Answer the following questions using your newfound knowledge about applying bivariate statistics and their p values to published results. Make sure you answer all parts of the question to get full credit.

In terms of independent variables, by referring to the Appendix, figure 1 reveals the summary of the sample; it also

To answer the questions listed above, data was needed, and this was sourced from the
