1. What does the paired-samples t-test test for? 2. The paired-samples t-test utilizes a within-subjects design. What is the main difference between a within-subjects design and a between subjects design? 3. What is the difference between a repeated measures and a matched design?
The test statistic for a related samples t-test is computed using a single sample of Options: Original data Standardized scores Raw scores Difference scores
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...
True or False? when sample data occurs in pairs, an advantage of choosing a paired t-test is that it tends to increase the power of a test, as compared to treating each sample independently. True or False? When testing the difference between two population proportions, it is necessary to use two samples with the same sample size. True or False? If the sample proportions are p1=6/90 and p2=4/100, we can assume normality for the two sample proportions in a test...
In a paired samples t test, explain the logic of difference scores (why do you need to find them to make conclusions about your research) and why do you compare it to a population mean often designated as zero (µ = 0)?
QUESTION 14 What is the paired-samples t test statistic for the following difference scores:-2.-19, +17, -22, -67 -6.40 -0.92 O 6.96 O 15.57
Because the scores across treatment conditions are necessarily related (as they are from the same subjects), we need to use the ____. Geoup of answers Matched design Pretest-posttest design Post hoc design Related/Paired samples t test In the ____, the difference scores for each subject/pair are calculated to use the data to be analysed Group of answers With-subjects/Paired samples t test Related/Paired samples t test Between-samples/Paired samples t test Between-subjects/Paired samples t test
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...
Explain why the assumption of equal variance is irrelevant for the paired-samples t-test.
Design your own study using one of the following statistical tests: one-sample t-test, paired samples t-test, independent samples t-test, or ANOVA. Give (1) your sample, (2) research question, (3) the appropriate test with the null and research hypotheses, and (4) the two variables, including (a) how you would measure both variables and (b) each variable’s level of measurement. Be creative. Do not include data in your response.
