Please help with the following multiple choice 1. In the one-way ANOVA where there are k treatments and n observations, the degrees of freedom for the F-statistic are equal to, respectively: a. n and k. b. k and n. c. n − k and k − 1. d. k − 1 and n − k. 2. In ANOVA, the F-test is the ratio of two sample variances. In the one-way ANOVA (completely randomized design), the variance used as a numerator...
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
6. The most basic statistical test that measures group difference is the T-test. 7. One-way analysis of variance (ANOVA) only determines the significance of group differences and does not identify which groups are significantly different. 8. One-way analysis of covariance (ANCOVA) is similar to ANOVA but additionally controls for a variable that may influence the DV. 9. Factorial analysis of variance (factorial ANOVA) extends ANOVA to research scenarios with two or more IVs that are categorical. 10. Factorial analysis of...
21. In one-factor ANOVA for independent samples, which of the following reflects a random variability of scores in the samples? A. MSbetween B. MStotal C. MSwithin D. A & B 22. A one-factor ANOVA is used to evaluate the mean differences in cognitive task performance between three experimental groups, with n = 15 participants in each group. If the computed F = 3.17, which of the following is the correct statistical decision? A. Reject the null hypothesis with either α...
4. Which of the following is an assumption of one-way ANOVA comparing samples from three or more experimental treatments? a. All the response variables within the k populations follow a normal distributions. b. The samples associated with each population are randomly selected and are independent from all other samples. c. The response variable within each of the k populations have equal variances. d. All of the above. 5. The t test for the difference between the means of two independent...
Match each research question below with the appropriate analysis: (independent samples t-test, dependent samples t-test, one-way ANOVA, or Chi-Square analysis). 1. Do cereals with a grade of A have significantly fewer calories per serving compared to those with a grade of B? 2. Is there a significant difference in the number of grams of carbohydrates and grams of protein within specific cereals? 3. Is there a significant difference in the ratings from cereals of different manufacturing brands?? 4. Is there...
QUESTION 11 For each of the examples below decide which statistical test should be used to analyze the data. You want to test the effect of one IV on a DV with three levels with different A. Z-test participants receiving each of the levels B. Pearson Correlation You want to compare a sample with a population, but don't know all of the population parameters C. Single sample t-test One group of participants took medicine, another group took a placebo pil...
A factor in a one-way ANOVA yields the same result as a t-test when a. there is one sample. b. there are two samples. c. there are more than 2 but less than three samples. d. there are more than three comparisons.
A within-subjects design is to the whereas a between-subjects design is to the a. Repeated-measures ANOVA; One-way ANOVA. b. One-way ANOVA; Chi-square test for independence, c. One-way ANOVA; Repeated-measures ANOVA. d. Dependent samples t-test; Repeated-measures ANOVA
