Unit 5 CA 5171 Unit 5b Just Hard Work—Statistics and the Thesis or Project Process Cool Bicycles

Unit 5 CA 5172 Statistics Chi-square—Compares groups frequency (nominal data) t- test –Compares means of two groups (interval data). ANOVA—Compares means of multiple groups (interval data). Correlation—Compares trends of two variables (interval data).

Unit 5 CA 5173 A Statistical Test Is Required to Test A Hypothesis!

Unit 5 CA 5174 Null Hypothesis The statistical hypothesis is sometimes called the Null Hypothesis. It is the hypothesis that is tested. There is no significant difference...

Unit 5 CA 5175 Picking a statistical test Need to know type of data (e.g., nominal, ordinal) Need to know nature of group comparison or variable relationship.

Unit 5 CA 5176 Decision-Making Study of statistics. Advisor’s advice. Statistics professor’s advice. Use a chart to guide you such as this one: htm htm

Unit 5 CA What do you do with your proposal now? Advisor to work with you through the process. Committee members. Obtain IRB Approval

Unit 5 CA Process Proposal and every chapter of thesis goes to the whole committee as you proceed. Keep committee informed about project as you go along. Committees don’t like surprises—and neither will you.
