Question

On a scatter diagram, the vertical distance between the actual score and the regression li represents the slope. regression constant. squared error. Error. when we use descriptive statistics, we are: manipulating independent variables experimentally. using random assignment experimental conditions. collecting, organizing, and presenting data. using data from a sample to answer questions about a population. Class standing is an example of a(n) ___ scale. ratio. interval. ordinal. Nominal. The squared coefficient of correlation is known as: correlation matrix. proportion of shared variance. squared variance. standardized regression coefficient. Grade Point Averages (GPA) are an example of a(n): nominal scale. ordinal scale. rank-order scale. equal interval scale. A distribution of 12 scores, has a mean = 45 and variance = 36, what is the standard deviation of the scores? 5 6 112.5 0.556 Which of the following statements is true? The standard deviation will always be larger than the variance. The standard deviation will always be a positive number. The standard deviation will always be larger than the range. The standard deviation will always have a small squared deviation. For the regression equation, cap Y = a + bX, which of the following X, Y points will be on the regression line a, b b, a 0, a 0, b A distribution can have more than one: median. mode. range. mean.

Explanation / Answer

8) D

9) C

10) C

11) D

12) D

13) B. We know that square root of variance is standard deviation. Hence if variance is 36, standard deviation would be 6

14) B

15) C. When we substitute the options, only option C satisfies the regression equation

16) A. When the number of items in the distribution is even, we can have two medians
