2. Look at the Independent samples t-test table to get your t calculated, df, and significance. Read the line that says “equal variances assumed”. Remember that significance level will appear in the Sig (2-tailed) column. Any value that is smaller than .05 will be significant at the .05 level or higher. In a sentence describe the results and report them in APA style, including r2 and evaluation (you will need to calculate r2 by hand).
3. What type of error in hypothesis testing is possible given the above result? How likely is this error given r2?

The output below is for a t-test for the hypothesis: Individuals living in bad neighborhoods commit more crime than those living in good neighborhoods. The data in the Group Statistics section provides you with the average number of crimes committed by individuals living in good and bad neighborhoods and the standard deviation of this same variable. The findings of significance are located in the Independent Samples Test section. Pay particular attention to the "t" column and the "Sig (2-tailed)"column. The...
Problem Set 1: The independent-samples t test Research Scenario: A learning psychologist is interested in comparing the success of two different mnemonics (memorization methods) on performance in a memory task. He assigns students to two groups, one which learns and uses a language-based rhyming memory technique, and one which learns and uses a visual “method of loci” spatial memory technique. He then administers a memory task to each group of students. The students are scored based on the percentage of...
