The major mode in the distribution of scores below is X = 5.

A characteristic, usually a numerical value, which describes a sample is called a _____.

In August in Florida, the daily high temperatures are typically high with only a few relatively cool days. A frequency distribution graph showing daily average temperatures in Florida for August would probably form a negatively skewed distribution.

If a researcher measures two individuals on an ordinal scale, it is possible to determine how much difference exists between the two people.

The median is the best measure of central tendency to use in order to describe the distribution of scores below pertaining to the average daily coffee consumption of a sample of individuals.   Daily Cups of Coffee Consumed (X)          f 4 or more                                                     2 3                                                                   2 2                                                                   1 1                                                                   3 0                                                                   3

A distribution of scores has a mean of 52, a median of 54, and a mode of 56. Based on this information, it appears that the distribution is symmetrical.

If a set of scores covers a range of 70 points, then the grouped frequency table for the scores should use an interval width of 7 points.

The median is considered to be the “balance point” for a distribution because it is the score for which the total distance between scores below the median and the median is identical to the total distance between scores above the median and the median.

A grouped frequency distribution table lists one interval as 15-20. The width of this interval is 5 points.
