18) A manipulated variable could also be called::* OA) Response variable OB) Explanatory variable OC) Dependent variable OD) Independent variable 38) The average speed limit in the US is 25 mph with a standard deviation of 2.4 mph. What is the probability that a speed limit in the US is greater than 20 mph?: OA) 18.8% OB) 1.88% OC) 98.12% OD) 81.2% 39) A recent magazine article states that in a study of 64 high school students, the average teenager...
Which is not true in ANCOVA? i. The covariate is continuous ii. The dependent variable is categorical iii. The independent variable is categorical iv. The response is continuous
If the regression slopes of the dependent variable (Y) on the covariate (X) are substantially different across the groups, one would expect that a. the adjusted means will be biased. b. Y is independent of X. c. the factor is not independent of X. d. there is a modest effect with equal n's in quasi-experiment.
Think of a dependent variable within your work environment, domain of interest, or everyday life that would be valuable to predict using multiple regression. What are some independent variables that you would include in the analysis when your intuition tells you they may be related to the dependent variable?
What is/are constant(s) within an experiment? Select one: a. Response (dependent) variables which must be kept the same throughout the experiment. b. Any variable, other than the explanatory (independent) variable, which is/are kept the same between treatments. c. Variables, other than the response (dependent variable), which are varied throughout the experiment. d. Explanatory (independent) variables which require controls.
In regression, we call Y the response or dependent variable, which is modeled in terms of one or more "independent" variables. The independent variables are further classified as explanatory/causal variables or as predictor variables. Discuss and elaborate on whether or not time can be a legitimate explanatory/causal variable, whether time can be a legitimate predictor variable whether a predictor variable must also be a causal/explanatory variable. Provide examples to support your arguments.

The difference between the observed value of the dependent variable and the value predicted by using the estimated regression equation is called _______ a. the variance b. a residual c. a prediction interval d. the standard error
In a regression analysis, the variable that is used to predict the dependent variable a. is the independent variable b. must have the same units as the variable doing the predicting c. is the dependent variable d. usually is denoted by x
Dummy Variable Regression: Choose any metric variable as the dependent variable (you can use the same one that you used in Part A) and choose gender as an independent variable. Also choose one more metric variable as an additional independent variable. Once again, however, you must sort through the metric independent variables until you find one that, along with gender, produces a significant F-calc. Use alpha = .05 here as well. You only need to report the model that produced...
