40.
Participants in the sample scored 5, 2, 43, 1, 48, 40, 45
What is median?
100
This is calculated by subtracting the lowest score from the highest score.
What is range?
100
The number of scores in a particular interval.
What is the frequency?
100
These kinds of distributions are non-symmetric.
What is skewed?
100
Honda, Ford, Mazda, GM, Nissan.

29
The participants in the sample have scores of 18, 42, 29, 36, 50, 29, 32
What is mode?
200
This is a measure of variability that corresponds to the average amount that scores in a sample deviate from the mean.
What is the standard deviation?
200
The number of scores in a particular interval and all the intervals lower than it.
What is the cumulative frequency?
200
Most of the scores in this type of distribution are clustered near the lower scores of the distribution.
What is a positively skewed distribution?
200
Distance in meters is what type of variable?
What is ratio?
300
In a normal distribution, these three are exactly the same.
What are the mean, median, and mode?
300
You calculate this measure of variability by squaring the standard deviation.
What is the variance.
300
A graph where bars represent the number of scores per interval.
What is a histogram?
300
This type of distribution has two "humps."
What is bimodal?
300
Sizes of shirts (XS,S,M,L,XL) are what type of variable?
What is ordinal?
400
20 is this.
The scores in the sample are:
10 10 25 25 30
What is the mean?
400
The number of standard deviations Tatiana scored above the mean if her score was 80, the mean was 50, and the standard deviation was 15.
What is 2?
400
This kind of graph is used with nominal level data.
What is a Pareto graph?
400

What type of variable is this?
What is interval?
500
The mean of this sample of scores:
16, 58, 26, 18, 32
What is 30?
500
This is the percentage of scores that fall within plus or minus 2 standard deviations of the mean.
What is 95%
500
In a frequency distribution table, (f/n x 100) gives you this.
What is the percentage?
500
What percentage of data falls within 3 standard deviations on a normal distribution?
99.7%
500
What is the difference between ratio and interval scales of measurement?
Interval: Zero is not a true zero (meaning: zero doesn't mean "nothing"). Ex: temperature
Ratio: Zero is a true zero (meaning: zero means "nothing"). Ex: time
