Look at the table for the Paired samples test to find your t calculated, df, and significance. 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...

Imagine that a researcher is conducting a paired-samples t test. She finds that the sample mean difference is 5, the standard deviation of the difference scores is 15, and the sample size is 85. The researcher is also using a typical null hypothesis that proposes no differences between the relevant population means. Under these circumstances, what is the value of the paired-samples t statistic? Please retain a minimum of three decimal places for all steps (if relevant) and provide a...
please please help, i'll give you thumbs up :) Paired Samples t-test Gregg Popovich, head coach of the San Antonio Spurs, had his top five scorers practice during the past week with the shooting coach Chip Engelland. They shot 100 free throws prior to working with Chip and then shot 100 free throws after working with Chip. Below are the total number of free throws made before and after working with Chip Engelland. Popovich wants to know if practicing with...
Twenty undergraduate students were given t Dependent Samples t-test Badate students were given two versions of a Sitem test. Half of the 20 weerst given the multiple choice version of the test They were then given the same test questions presented in open-ended form s presented in open-ended form (without choices). The other half were given open-ended form of the test first followed by the multiple-choice version. The data Ociow list the number of correct answers on each test for...

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...
