Five students were tested before and after taking a class to improve their study habits. They were given articles to read which contained a known number of facts in each story. After the story each student listed as many facts as he/she could recall. The following data was recorded. The researcher is wondering whether the class will help students recall more facts. What statistical test will you use to test the researcher's hypothesis? BEFORE 10 12 14 16 12 AFTER 15 14 17 17 20 A. t-test for correlated groups B. t-test for single samples C. t-test for independent groups D. One-way ANOVA E. Chi-square F. Z-test for single samples

As a researcher, you are interested in examining the effect of high school students' study habits on final exam grades in math courses. Below are the exam scores for the sample of students with different types of study habits: - Practice Problems Only - Reads Notes Only - Reads Notes & Practice Problems - Does Not Study Which is the independent variable, and which is the dependent variable? The dependent variable is the grades in the math course. The independent variable is the study habits. What is your null and research hypothesis? Null hypothesis: All four groups have the same mean. Alternative hypothesis: The mean of at least one group is different. Ho: ÎĽ1 = ÎĽ2 = ÎĽ3 = ÎĽ4 Which test should you use (Two Sample Independent ANOVA, Chi-square, correlation)? ANOVA Calculate the test statistic.

An educational researcher wanted to test and compare the impact of three different learning environments on children's confidence with math. She randomly selected 24 students and then randomly divided this group into three subgroups: a 'Placebo' group who did a math test in their usual classroom environment; an 'Outdoor' group who did a math test in an outdoor setting within the school grounds; and a 'Chill out' group who did a math test in a 'chill out' space within the school, that had dimmed lighting, music, and casual seating. The children spent one hour within their settings, and their math scores were recorded at the end of the test. What sort of statistical test should be conducted on this data? a. Repeated-measures ANOVA. b. One-way ANOVA. c. Correlation. d. Multiple linear regression.
