Subject:BiologyPrice: Bought3
A researcher designs a new app to help children with ADHD improve their social skills. She randomly assigns 100 children with ADHD to either use the new app for 3 hours per week for a month (the experimental group) or to a control group that does not use the app and then compares their social skills. The researcher expects that social skills will be better in the experimental group than in the control group.
What is the most appropriate test statistic to use to test the hypothesis in scenario 1?
Group of answer choices
a. Structural Equation Model
b. One-way ANOVA
c. Correlation Coefficient
d. Dependent samples t-Test
e. Factor Analysis
f. z-test
g. Independent samples t-Test
h. z-score
What is the null hypothesis for scenario 1?
Group of answer choices
a. H0: social skills in the experimental group ≤ social skills in the control group
b. H0: rxy = 0
c. H0: social skills in the experimental group ≠ social skills in the control group
d. H0: µ1(group that does the new program) = µ2(control group 1) =µ3(control group 2)
e. H0 : social skills in the experimental group = social skills in the control group
What is the alternative hypothesis for scenario 1?
Group of answer choices
a. H1: social skills in the experimental group > social skills in the control group
b. H1: social skills in the experimental group = social skills in the control group
c. H1: social skills in the experimental group < social skills in the control group
d. H1: social skills in the experimental group ≠ social skills in the control group
e. H1: µ1(experimental group) ≠µ2(control group 1)≠µ3(control group 2)
f. H1: rxy = 0
What is the independent variable for scenario 1?
Group of answer choices
a. The researchers
b. The children
c. Social skills
d. There is no IV for this type of analysis
e. The social skills app
What is the dependent variable for scenario 1?
Group of answer choices
