11) The standard error of estimate conceptually refers to the square root of "average"

squared deviation of scores from the regression line (TrueFalse)

12) Psychological measurement refers to assignment of a numerical value to an object or

an event (TrueFalse)

13) Fahrenheit used to measure temperature is an example of an interval scale (TrueFalse)

14) The sum of squared deviation scores about the mean should add up to zero (True False)

15) In order to convert a continuous variable into a categorical variable by using

SPSS, we need to select "compute variable" function on the menu (TrueFalse)

16) Correlation indicates a specific causal relationship between two variables (TrueFalse)

17) If all the data points are negative numbers, the standard deviation of them can be a

negative number(TrueFalse)

18) A correlation coefficient of two variables has the same value as the slope of the

regression equation from those variables if they are standardized (TrueFalse)

19) When a constant is subtracted from each data point, there is no change in the standard

deviation (TrueFalse)

20)Because z-scores can be considered conceptually as an example of "interval" scale, the

proportion between z = -1 and z = 0 would be identical to the proportion between z = 1 and z = 2 (given a standard normal distribution)(TrueFalse)
