When one variable causes change in another, we call the first variable the ___________________ variable*. The affected variable is called the _______________ variable*. : When one variable 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 explanatory variable and measures the resulting changes in the response variable. The differe...

In a standard 52-card deck, where each card is assigned a numeric value, the mean of the 52 cards is 7.0 with a standard deviation of 3.742. To test if a representative sample can be attained, the deck is shuffled and 13 cards are randomly drawn, one at a time. Each card is recorded and then returned randomly to the deck before the next card is drawn. This process of drawing 13 random cards is repeated a total of 20 times, and the mean and standard deviation of each round is computed. Which...

lurking variable - correct answer A variable that is not included in an analysis but that is related to two (or more) other associated variables which were analyzed. simple linear regression - correct answer the prediction of one response variable's value from one explanatory variable's value Simpson's Paradox - correct answer A counterintuitive situation in which a trend...
