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.

* For large samples one sample t-tests (n >120) use critical t scores of ±1.96 (for 95% confidence level two tailed test) or ±1.65 (for 95% confidence level one tailed test). * For small samples (n<120) use critical t score obtained from t-distribution table. You will need to calculate degrees of freedom, which is simply the sample size minus 1 (df = n-1) and use an alpha value of .05. * For comparing means between two samples (regardless of sample...

Find the critical value of t from Appendix D for the following situations. Specify the correct degrees of freedom, whether the value is “+/-“ or is “+ or –“ and the df you used in the table if the value isn’t listed. a) N = 32, α = .05, one-tailed independent groups t-test b) N = 28, α = .01, two-tailed independent groups t-test c) N = 26, α = .05, one-tailed independent groups t-test d) N = 41, α...

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).

When should I use the One-sample t-test? Remember that some tests, such as chi squared, can be used under various circumstances. The goal of the test changes based on the situation. Pay attention to the specific conditions noted in parenthesis to ensure you are picking the correct goal. A. Test the fit of the normal distribution to the data set. B. Compare two treatment groups consisting of independent samples with a normal distribution AND unequal variance. C. Test to see...

For the following experiment/question, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all. Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption. This means you must...
