Exam 13: Analysis & Interpretation: Multiple Variables Simultaneously

The manager of New England Patriots conducted a large survey. He wanted to know if there was an association between fans being "season ticket holders" vs. "non-season ticket holders" and whether they "bought" vs. "didn't buy" team merchandise at the game. Since his survey included these measurements, he used SPSS to run a Pearson correlation coefficient that turned out to be 0.88 with a Sig. value of .001. This meant there is a significant relationship.

The simple regression technique in SPSS, not the researcher, specifies which variable should be the independent variable and which one should be the dependent variable.

Which of the following emphasizes the division of the sample into subgroups so as to learn how the dependent variable varies from subgroup to subgroup?

A statistic used to measure the strength of relationship between categorical variables is called a(n) ____________________.

If the F-value in ANOVA produces a significantly high p-value (a.k.a. "Sig." in SPSS) of 0.11 or more, then it is appropriate to proceed with a post-hoc test (e.g., Duncan).

Which of the following concerning the Pearson chi-square test is FALSE?

Cross tabulation work equally will with continuous measures that have been recast as categorical measures.

Which of the assumptions listed below are necessary, in order for the coefficients in a partial regression equation to be interpreted as the average change in the criterion variable associated with a unit change in the appropriate predictor variable holding other predictor variables constant?

The NFL office discovered data covering attendance at professional football games in the late 1940s and early 1950s. The game with the highest attendance was between the St. Louis Cardinals and the New York Giants. The office also found considerable information that someone had collected on each game day such as the level of GDP, the DOW, numbers of persons employed, number of new businesses formed during the week preceding the game, and the population. A student intern took the information and built a regression model to predict game attendance for the upcoming season. The model should:

-Refer to Exhibit 13.1. What relationship can be inferred from the above table between family size and owing a microwave?

In a regression analysis, determining the statistical significance of the slope involves the use of the t-statistic.

The coefficient of determination represents the relative proportion of the total variation in the outcome variable that can be accounted for by the predictor variable in the regression.

Analysis of variance (ANOVA) is most applicable when there:

A gas station wants to compare a group of consumers' overall perceptions of service with overall perceptions of service for a nearby competitor. This situation calls for the use of:

Which of the following is FALSE about cross tabulations?

-Refer to Exhibit 13.1. The most appropriate way to calculate percentages in the above table to reflect cause and effect is by dividing

Carters, a marketer of children appeal, knows that as girls increase in age, their dress size tends to get larger. This is an example of a causal type of relationship?

Which statistical technique should you use when you are attempting to answer the question: "Is there a significant relationship between the customers' disposable income (measured in dollars) and their repeat-buying behavior (measured by the number of rebuys in a twelve-month period)?"

Which of the following is a technique that measures the association between a criterion variable and one or more independent variables?

The magnitude of the Pearson correlation coefficient indicates the direction of association, while its sign indicates the strength of the association.
