What does ANOVA stand for? Analysis of variance When is it appropriate to use an ANOVA? When a dataset is made up of three or more groups. Which of the following is a TRUE statement regarding an ANOVA? The F ratio compares the variance within samples to the variance between samples. 3 multiple choice options The determines the type of ANOVA to run on a dataset. number of factors (independent variables) Which of the following items are needed in order to locate the critical value for an ANOVA using the table? Select all that apply.

dfbn,dfwn,significance level True or False: An economist wants to compare the mean annual income of employees at four Fortune 500 companies. Analysis of variance cannot be used because there are more than three populations. False An ANOVA can be used for research designs with three or more groups. Samples of theme park wait times are obtained and compared. Five major theme parks are compared, and their mean wait times are recorded. Identify the null hypothesis and alternative hypotheses for applying an analysis of variance. Ho: All five theme parks have the same mean wait times. Ha: At least one of the five theme parks has a mean wait time that is different from the others. What does an F-value below 1 indicate? What does an F-value above 1 mean? Answer: A small F (F < 1) indicates that the variation within the groups is greater than the variation between group means. In contrast, a large F (F > 1) indicates that the variation between the group means is greater than the variation within the groups. The greater the value of F, the more likely it is that a true difference exists between the group means.

What is the term used to describe complex experimental designs that investigate the effects of more than one independent variable? Factorial designs A effect is the individual effect of each variable in a two-way ANOVA, whereas the effect is the combined effect of independent variables. Main; interaction True or False: A two-way ANOVA involves calculating a single F statistic to determine if there is a statistically significant difference in the means. False; a two-way ANOVA calculates 3 different F ratios: one for each main effect and one for the interaction effect. Which of the following statements is TRUE? A two-way ANOVA is almost exclusively performed using statistical software. The calculations involved in a two-way ANOVA are tedious and time-consuming, so it is preferable to use statistical software to run this type of analysis.

A refers to an independent variable in an ANOVA, whereas a refers to each treatment condition. Factor; level A person lives in a home with a solar electric system. At the same time each day, she collects voltage readings (in volts) from a meter connected to the system. The results are listed in the table below. A one-way ANOVA is used to analyze the differences between these three group means. The results are shown below. a. State the null and alternative hypotheses for this test. b. Interpret the results. c. What does the effect size measure indicate? a.) H0: μSunny=μCloudy=μRainy Ha: At least one of the means is different from the others b.) Answer: The results indicate a statistically significant F-value because p < 0.001. Therefore, the null hypothesis is rejected. There is sufficient evidence to support a claim of different group means.
