Multiplying rf by 100 yields frequency.

A table showing each score in a set of scores and the number of times it occurred is called a.

The midpoint of a class interval is midway between the limits of the interval.

The formula ( f of scores in interval) N provides the grouped frequency.

A percentile is.

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

Listing each possible score value and then placing a tally mark next to each score for each time it occurs in a set of scores results in a(n) frequency distribution.

The scores of a subject exactly as collected and before they are analyzed statistically are called.

The formula (Xhighest - Xlowest) ⁄ number of intervals provides the in a grouped frequency distribution.

An examination that clearly distinguished between those students who knew the material and those who did not would most likely yield a distribution.

The formula (rf of scores in interval) × 100 provides the grouped frequency.

The symbol crf represents the frequency.

In a(n) frequency distribution, scores are placed into.

In a histogram, the the class interval is given by the height of the bar.

An examination that is so difficult that many people get low scores and only a few get high scores would create a.

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

A bar graph is used to present data, whereas a histogram is used to present data.

The size of a class interval in a grouped frequency distribution is represented by.

The symbol c%f represents the frequency.

If the 40th percentile on an examination is 75, then.
