Exam 3: Looking at Data: Frequency Distributions and Graphs

A frequency distribution most easily allows comparisons between two distributions of scores with a different number of scores in each distribution.

The relative location of a score in a distribution is indicated by its.

The frequency of a particular score divided by the total number of scores in the distribution is the frequency of a score.

The symbol f in an ungrouped frequency distribution is used to represent the.

The symmetrical bell-shaped frequency distribution is also known as the distribution.

The normal distribution is.

For the class interval of 20-25, the upper real limit is.

In a histogram, the is represented by the width of the bar on the abscissa.

When plotting a graph of a frequency distribution, the is/are placed on the X axis.

Dividing the difference between the largest score and the smallest score in a distribution by the number of class intervals yields the of the class interval.

When looking at a graph, a Y-axis with no numbers.

Connecting dots indicating the frequency at the midpoints of class intervals with straight lines yields a.

The grouped percentage frequency is determined by.

If a distribution has scores clustered more at one end than at the other, then the distribution is.

A bimodal distribution has "peaks."

If the computed class interval for a frequency distribution is equal to 4.25, then the actual class interval used should be.

The height of a vertical bar is used to represent the frequency of occurrence of scores in a .

Dividing the frequency of scores in an interval by the total number of scores in a grouped frequency distribution yields the grouped frequency.

For the class interval of 20-25, the lower stated limit is.

The grouped relative frequency of a class interval plus the sum of the relative frequencies of all lower class intervals is the frequency of a distribution.
