Exam 3: Looking at Data: Frequency Distributions and Graphs

If more scores are clustered at the high-score end of a distribution and only a few scores are at the low-score end, then the distribution is.

The total number of scores collected from a group of participants is identified by .

The formula for the percentage frequency of a score in a distribution is given by.

When thinking about the accuracy of a graph,

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

The percentile rank of Jaima's score on a statistics exam was 83. This value indicates that .

For the class interval of 10-15, the lower stated limit is ; whereas the lower real limit is.

Dividing the frequency of a score by the total number of scores in the distribution of scores will yield the of a score.

The midpoint of the class interval 30 to 34 is.

Suppose an examination was very easy and all but a few students obtained a high grade on it. The frequency distribution of these scores would be.

The number of class intervals used in constructing a grouped frequency distribution typically is between.

For the class interval of 10-15, the upper stated limit is ; whereas the upper real limit is.

If the 30th percentile on an examination is 65, then.

The symbol % f is used to represent the of a score in a distribution.

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

A distribution in which one side is the mirror image of the other side is.

In a grouped frequency distribution, the range of score values into which the raw scores are grouped is called the.

If more scores are clustered toward the low end of a frequency distribution and only a few scores are at the high end, then the distribution is.

A percentile is used to describe the a distribution.
