An ANOVA comparing two groups is equivalent to an independent samples t-test.
True
False
This statement is True because we will be comparing the means of two different populations in both the cases.
An ANOVA comparing two groups is equivalent to an independent samples t-test. True False
QUESTION 11 You run an independent samples t-test between two groups, and find a t-statistic of t=1.67. Is this sufficient to reject the null hypothesis? Assume α=0.05 and a one-sided test. Yes, > 1.67 is sufficient to reject the null. No, > 1.67 is not sufficient to reject the null. Not enough information. 2 points QUESTION 12 In a dependent samples t-test, the sample sizes must be equal. True False 2 points QUESTION 13 In an independent samples...
an anova hypothesis test is equivalent to conducting two sample t-test between every pair of samples. if there are three samples, there are three pairs:1-2,1-3, 2-3. how many pairs are there when there are 4 samples?
Question 1 (1 point) When we compute an independent-samples t-test, we are looking to see if there are significant differences between the means of two independent groups, each measured on a different level of the independent variable. al True b) False Question 2 (2 points) When we compute a paired-samples &-test, we are looking to see if there are significant differences between the means of two independent groups, each measured on a different level of the independent variable. a) True...
The F test in one-way ANOVA models is just an expansion of the t test for independent samples. Select one: a. FALSE b. NEITHER c. TRUE
Question 2 1 pts For an independent-measures ANOVA comparing four treatment conditions, dfbetween=3. True False Next For an analysis of variance comparing four treatment means with a separate sample of a participants in each treatment, the F-ratio will have df - 3.31, 8 True False Next →
1. When do we use an independent groups t-test? a. b. c. d. When we are comparing means from one sample that has been measured twice. When we are comparing means from two different samples. When we are comparing a sample mean to a population mean. When we are comparing two population means. 2. Which of the following is true regarding the use of t-tests for true experiments versus quasi-experimental designs? a. b. We use the same t-test whether it...
If you are using SPSS to conduct a two independent samples t-test, examining the impact of your independent variable of "smoking status" (smoker vs. non-smoker) on your dependent variable of "number of cavities reported in a 3 year period", the variable of "smoking status" would be your identified "Grouping Variable" in the Independent Samples T-Test pop up box. Is this true or false?

Keep the Highest: Attempts: /4.5 7. Comparing ANOVA and the t test for an independent-measures hypothesis test Aa Aa Suzanne Zeedyk, a developmental psychologist at Dundee University's School of Psychology, conducted a pilot study in which parents started a half-hour walk with their infants in a parent-facing or an away-facing stroller and then switched to the other type of stroller midway. Her results suggest that parents talked less to the babies, the babies...
Compare and contrast the differences between a single sample t test and an independent samples t test. Next describe a hypothetical study using the design of an independent samples t test. List the two groups that you would test.
11. What is the null hypothesis for a t-test for two independent groups? a. If mul and mu2 are the population means of the two groups, then the null hypothesis is Ho: mul-mu2=0. b. If sl and s2 are the population standard deviations of the two groups, then the null hypothesis is Ho: sl-s2=0. 12. Differentiate between a data set that should be analyzed using a paired t-test from a data set that should be analyzed using a t-test for...
