Answer to Question 1

ANS: C
In a skewed distribution, the mean, median, and mode are not equal. In a negatively skewed distribution, the mean will be less than the median, which will be less than the mode.

Answer to Question 2

ANS: A
The measures of central tendency are descriptive statistics. The statistics that represent measures of central tendency are the mean, median, and mode. All of these statistics are representations or descriptions of the center or middle of a frequency distribution. The mean is the arithmetic average of all of a variable's values. The median is the exact middle value (or the average of the middle two values if there is an even number of observations). The mode is the most commonly occurring value in a data set. In a normal curve, the mean, median, and mode will be equal or approximately equal
