When graphing data, it is traditional to make the length of the ordinate equal to

When a distribution shows a large majority of very low scores and a few very high scores, the distribution is said to be
Multiple Choice
The ordinate is identical to the

The influence of a few extreme scores in one direction is most pronounced on the value of the
Multiple Choice
When single points are used to designate the frequency of each score, the points being connected by a series of straight lines, this is called a
Multiple Choice
When each score is listed in order of magnitude, together with the number of individuals receiving each score, the researcher has set up
Multiple Choice
The measurement which occurs most often in a distribution is called the

When a graph is constructed using a series of rectangles indicating the frequency of occurrence for each score, it is called a
Multiple Choice
When a distribution is skewed, the researcher who is interested in central tendency should use the
