Answer #1

Answer:

Independent Variable: Hypnotic analgesia is the independent variable, as the psychologist is controlling and changing it to study its effectiveness through two groups of subjects (experimental and control groups, with use of analgesia and no use of analgesia respectively).

Dependent Variable: The duration of pain relief in a hypnotized state is the dependent variable, as it is being measured by checking the amount of time each subject can hold his/her hand in an ice water bucket. The data comparison for both groups will display the effectiveness of the independent variable.

Explanation: An important aspect to identify an independent variable is that it is the variable whose effect is being studied and it is the variable that is being changed to see the effect on the dependent variable. Now, the dependent variable is the one that is actually being tested and that is dependent on the independent variable. The dependent variable is being measured after variations made in the independent variable. From this perspective, the above-mentioned are the identified variables in the given study.

An experiment was done to test the effectiveness of a drug that is being considered for possible use in the treatment of people who experience chronic anxiety. Fifty people who are chronically anxious are identified through a local health clinic. Twenty-five people are randomly assigned to the experimental group, and they receive the new drug for six weeks. The other 25 people are randomly assigned to the control group, and they receive the commonly used drug for six weeks. After...

To test the effectiveness of a studying program, participants are randomly assigned to either the control group or the treatment group (N=10 for each). At the end of the trials, the average test score increase in the control group is 3.5 points (s=0.7) and the treatment group increased 1.9 (s=1.1). Test the null hypothesis that there is no difference in test score improvement between the treatment and control groups (alpha = 0.05). For independent sample t-tests: mean values for each...

Experiment 1: Billy Rae Thompson wanted to test a new "singalong" method to teach math to sixth graders (e.g., "All the integers, are natural numbers" to the tune of "Call me Maybe"). He used the singalong method in his first period class. His sixth period students continued solving math problems with the old method. At the end of the term, Mr. Rogers found that the first period class scored significantly lower than the sixth period class on a mathematics achievement...

A researcher wants to evaluate the pain relief effectiveness of a new medication for chronic pain sufferers. Using a pain scale from 0 to 10 (where 0 = no pain at all, and 10 = the most pain you can imagine), she compares the pain level for a sample of n1 = 4 people who received the new medication, with the pain level for a sample of n2 = 4 people who received a placebo. The data are as follows:...
