- A researcher is interested in comparing two medications in order to see which contributes to the greatest decrease in symptoms as measured by an instrument on a scale of 0-100. The researcher recruits three groups of participants, one who receive medication A, one group of participants who receive medication B, and a control group who receives a placebo.
A. What type of study design is this (descriptive, correlational, or experimental)?
B. What would be the appropriate statistical analysis to use in that situation (Chi-Square, Pearson correlation, one sample t-test, paired samples t-test, independent samples t-test, or ANOVA)?
Homework Answers
A) The type of study design is correlational.
Correlational research involves the measurement of two or more relevant variables and an assessment of the relationship between or among those variables. The types of groups with medication A and B are the variables here.
B) Pearson correlation (Multiple Correlation) would be the appropriate statistical analysis to use in that situation.
We will use Pearson correlation (Multiple Correlation) as we have more than two variables.

A researcher is interested in seeing if playing violent video games leads to a change in aggressive attitudes. The researcher recruits an experimental group, who plays a violent video game for 1 hour, and a control group. Both groups complete a measurement instrument that measures their aggressive attitudes on a scale of 0-100. A. What type of study design is this (descriptive, correlational, or experimental)? B. What would be the appropriate statistical analysis to use in that situation (Chi-Square, Pearson...

A researcher is interested in whether a person’s gender is related to their favorite subject in school. The researcher records how many male and female participants are in the study and whether they prefer English, Math, or Science. A. What type of study design is this (descriptive, correlational, or experimental)? B. What would be the appropriate statistical analysis to use in that situation (Chi-Square, Pearson correlation, one sample t-test, paired samples t-test, independent samples t-test, or ANOVA)?

-It would not be appropriate to use the Mann–Whitney U test when: a researcher is comparing two independent populations. the dependent variable is measured at the ordinal level. the assumptions for an independent-samples t test are not met. a researcher is comparing three or more groups on a normally distributed dependent variable. -Kia assesses people's levels of gratitude and stress that occur naturally to determine if a relationship exists between the two variables.

q27 A research team is studying a new pain medication for patients suffering from fibromyalgia. Patients suffering from chronic pain as a result of fibromyalgia were divided into two categories: Treatment and Placebo. Patients in the treatment group were injected with the new drug while patients in the placebo group were injected with saline solution. Neither the patients, nor the health care practitioners admininstering the study knew who was receiving the actual drug. After two weeks the patients were asked...
