Question

Choose two statistical test (independent t-test, dependent t-test, ANOVA) and write down the steps for computing the statistical tests.

Answer #1

Determine whether you would use an independent t-test, dependent
t-test, or ANOVA with the following:
a. You have one qualitative independent variable, two levels, a
quantitative dependent variable and different participants in each
level
. b. You have two qualitative independent variables, two levels
each, and a quantitative dependent variable.
c. You have one qualitative independent variable, two levels, a
quantitative dependent variable and same participants in each
level.

-When you should use a dependent t-test vs. independent t-test
vs. Anova?

What is the appropriate statistical analysis to use: t-test for
two independent samples, t-test for dependent samples, ANOVA, or
chi-square test of independence? Please identify and explain why it
is appropriate. (a) A study was conducted to see whether monetary
incentives to use less water during times of drought had an effect
on water usage. Sixty single-family homeowners were randomly
assigned to one of two groups: 1) monetary incentives and 2) no
monetary incentives. At the end of three months,...

independent means.

A. fail to reject the null hypothesis.
B. reject the null hypothesis. There is...

HW 6: z-test, t-test for independent samples, t-test for related
samples, 1-way ANOVA
Researchers wanted to explore different treatment methods to
effect memory skills in high school freshmen. Subjects were given a
memory test (under multiple conditions) these were the results:
Group 1
10, 8, 9, 11,
8, 9, 7, 6,
9, 8
Group 2
12, 10,
11, 9, 13, 8, 9, 12, 11, 11
Group 3
10, 9, 10, 9, 11,
8, 7, 9, 10, 11...

What causes the p-value to be the same in an independent sample
t-test and as a one-way ANOVA?
1. Is it because dependent variables are the same while the
independent variable is different across the two methods?
2. Because ANOVA is a special case of the independent samples
t-test.
