The percent frequency or probability of a data value appearing.
What is Relative Frequency Table?
300
This is a special percentile that divides the ordered data set into 4 equal parts. Each equal part is 25%.
What is Quartiles?
300
1. Find the mean of the data set
2. Determine how far each term is from the mean
3. Add your values from Step 2.
4. Divide your sum from Step 3 by the number of terms in the data set.
What is the steps to find the MAD?
300
This plot arranges data by dividing each data value into two parts. It allows you to see each data value.
What is Stem-and-Leaf plot?
300
A box plot can present a good representation of a data set's distribution. For a ________ distribution, the median should be close to the middle of the box and the two whiskers should be about the same length.
What is normal?

What is a useful way to organize data that can be categorized by two variables?
400
Consists of the minimum, maximum, lower quartile, upper quartile, and the median of a data set.
What is the 5-number summary?

What is the MAD?
What is 9.28?
400
The measures of central tendency to identify different real world situations. The three common measures of central tendency are the mode, the median, and the mean.
What is Frequency Bar Graphs?
400
The distribution has a longer tail on the left.
What is skewed left?
400
Shows the frequency of all data values less than or equal to a given value.
What is Cumulative frequency?
500
Find the 5-number summary for the following data set:
