-------- Programmed Instruction for the Mean, Medium, and Mode --------
1. Data, by itself, would be of little use to a researcher
unless she had certain procedures for describing or analyzing
it. A list of 1,000 test scores can be an overwhelming sight.
2. Procedures used to analyze data are called statistics. One
important function of statistics is to provide useful
information from the raw data.
3. Procedures used to extract information out of a large
number of scores are called __________________.
4. A group of scores can be described in terms of some measure
of central tendency. Measures of central tendency provide
information about the typical or average score. statistics
5. Measures of central tendency are used to find the
_________________ score.
6. There are three common ways to find a measure of central
tendency. They are the mean, the medium, and the mode. typical
or average
7. The average score in a distribution is found by using a
measure of _____________ .
8. The mean is the most familiar to many people. It is often
called the average, but its technical name is the mean. It is
found by adding all scores and dividing the sum by the number of
cases. central
tendency
9. The medium is the middle-most score when all scores have
been arranged in order of size. The medium is the point that
bisects the distribution, half the cases falling above it and
half below it.
10. The mode is the most frequent score.
11. The three most common ways of finding a measure of central
tendency are the __________________, the __________________, and
the __________________.
12. What is the medium in this distribution?
58 55 52 50 47 47 41 mean
medium
mode
13. What is the mode in the above distribution? 52
14. The mean is found by first adding up all the scores in the 47
distribution and then dividing the sum by the number of scores
in the distribution. The computation for the above distribution
is shown below.
58 + 55 + 50 + 52 + 47 + 47 + 41 = 350 First, add the scores together
350 / 7 = 50 Second, divide the total by the total number of scores
The mean is 50
15. What is the mean for the following distribution?
25 25 15 15 10
16. The mean, medium, and mode provide a single, most typical 18
or representative score to characterize the performance of the
entire group.
