| Simple Regression |
In statistics, linear regression is a linear approach to modelling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables). The case of one explanatory variable is called simple linear regression.

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.

A week-long study of weight change, exercise, and caloric intake was conducted among a sample of members at a local gym. The variables are as follows: DV = weight change in pounds during the week IV1 = mean number of hours of aerobic exercise each day IV2 = mean number of calories eaten each day Note that weight change is defined as the difference between one's weight at the beginning of the week and one's weight at the end of...

The following 4 questions refer to Scenario 4. Generally speaking, people are pretty bad at telling whether or not someone is lying. Researchers are interested in studying if age is associated with ability to tell if someone is lying. Researchers compare a group of children (ages 8-10), adolescents (ages 14-17), and adults (ages 25-45) on their ability to tell if a person in a recorded video is lying or telling the truth. 1. What is the null hypothesis for scenario...

For each example, state whether the one-sample, the two-independent-sample, or the related samples t-test is most appropriate. If it is a related samples t-test, indicate whether the test is a repeated measures design or a matched-pairs design. 1) A researcher matches right-handed and left-handed siblings to test whether right-handed siblings express greater emotional intelligence than left-handed siblings. A. one-sample t-test B. two-independent sample t-test C. related samples t-test using the repeated measures design D. related samples t-test using the matched-pairs...

Hello if someone could help me with this multi part probably for the statistics? Thank you! Question 32q: A researcher is comparing two different weight-loss drugs. She splits her study participants into two halves randomly; every day for a month, one half (Group 1) takes Drug 1, and the other half (Group 2) takes Drug 2. She measures the total weight loss, in pounds, of each participant. A) Total Weight Loss of Each Participant at the end of the study...
