Answer: d) Grubb's test, F-test, t-test
Explanation: When conducting statistical comparisons on data sets, the order of tests we us as: Grubb's test, F-test, t-test. First by using Grubb's test we detect the outliers in the data. Secondly by using F-test we check the variances of two populations are equal or not. And Finally by using the t-test we compare the means of two populations equal or not.

All the procedures should be done with 5% P-value or 95% confidence interval Open Brain data. SETUP: Common sense dictates that a person’s IQ and Weight should not be related. However, one never knows until one examines the data. Given the data your job is to check if the common sense assumption is reasonable or maybe it is not. 13. What...

When should I use the Paired 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. Compare two treatments consisting of paired data where a normal distribution can be assumed B. Test the fit of the normal distribution to the data set. C. Compare two treatment groups...

I'm confused on how to approach this question, what statistical tests should I run to receive the required information? The data related to the health knowledge assessment scores in continuous and the variables it should be tested against are categorical. Test the association between the student’s health knowledge assessment score and the demographic variables (Gender, Race, and Family Income) and the behavior variables (Body Image, Sexual Activity, and Risk Behavior). Quantify the magnitude and significance of the association between the...

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...

Use Random number generator (under Data Analysis) to create two sets of data each 20 points long. Use the following parameters: number of variables (2), number of data point (20), Distribution (Normal), Mean (20), Standard Deviation (5), Random seed (4565). Perform t-test on these two data sets. And answer the questions for Assessment. (Pick the closest answer) 1. What is the range P-value? a. Between 0% and 1% b. Between 1% and 2% c. Between 2% and 3% d. None...
