WGU C784 STATISTICS MOD 5 2024 QUESTIONS WITH CORRECT ANSWERS ALREADY PASSED AND VERIFIED 1. When one variable causes change in another, we call the first variable the variable*. The affected variable is called the variable*.: When one vari-able causes change in another, we call the first variable the explanatory variable*. The affected variable is called the response variable*. In a randomized experiment, the researcher manipulates values of the explanatoryvariable and measures the resulting changes in the response variable.The differentvalues of the explanatory variable are called treatments. An experimental unit is a single object or individual to be measured. 2. A two-way table, also known as a two-way frequency table or contingency table, is used to show the relationship between two variables ( C’C ); the rows show the categories of one variable, and the columns show the categories of the other variable.: cat-egorical variables ( C’C ) 3. . These represent the total number of instancesthat fall in both the corresponding row and header. The data in the green cells show .These are equal to the sum of the number of individuals in the corresponding row or column.: The cells in yellow show joint frequencies*. These represent the total number of instances that fall in both the corresponding row and header. For example, data in the "Male" row and "With Autism" column counts the numberof males with autism. The data in the green cells show marginal frequencies*.These are equal to the sumof the number of individuals in the corresponding row or column. For example, datain the "Totals" column and "Female" row shows the total number of females in the study.It may be helpful to rememberthat marginal frequencies appearin the marginsof the table. WGU C784 STATISTICS MOD 5 2024 QUESTIONS WITH CORRECT ANSWERS ALREADY PASSED AND VERIFIED The bottom, right cell (in both the "Totals" column and the "Totals" row) measuresthe total number of individuals in the study. 4. The relationship between two variables that are both quantitative can bedisplayed in a .: scatterplot; 5. As we've seen earlier, every point on a coordinate plane can be repre-sented by an ordered pair*, ( x , y ). Here, the x -value is typically the variable's value for a piece of data, and the y -value is the corresponding value for the variable.A simpleway to remember this fact is that the term "explanatory" has an " x " in it.: explanatory variable; response variable 6. Side-by-side box plots are a good choice for two-variable data where the explanatory variable is data and the response variable is data.: Categorical Quantitative 7. Which variable, explanatory or response, is displayed on the x -axis on side-by-side boxplots?: Side-by-side boxplots can be horizontal or vertical, soeither variable (explanatory or response) can be displayed on the x -axis. 8. 9. A scatterplot is a good choice to display two-variable data that are both variables.: Quantitative 10. The relationship between the x -variable and the y -variable is called .: Correlation
