Measures of Center/Variability
Subtracting the minimum from the maximum to find this.
What is the range?
The part of a stem-and-leaf plot that helps you interpret the data points.
What is the key?
The bars of a histogram represent this in a set of numbers.
What is a range?
The minimum is located at this point on a box plot.
What is the farthest left point of the center line?
Favorite books, ice cream, or coffee are examples of this.
What is categorical data?
The steps for finding the median
What is ordering data points (numbers) from least to greatest and finding the middle data point (number)
A number line is used to organize the data of this type of graphic.
What is a dot plot?
What is symmetrical?
The maximum is located at this point on a box plot.
What is the farthest point on the right of the line?
Numbers given on frequency tables can be used to calculate this.
What are percentages?
The data point that repeats most often
What is the mode?
x
x x x
x x x x x__________________________________________

The dot plot above has this many data points
What is 9?
If the tail of a histogram is on the right it is known as this.
What is positively skewed?
The median is represented by this vertical line.
What is the second (center/middle) vertical line?
Given the percentage and the whole you can calculate this using multiplication.
What is the part?

The mean of the above dot plot is this
What is 3?
The amount of data points in each range can be found by counting along this axis.
What is the y-axis?
To find the IQR you must do this.
What is subtract the first quartile from the third quartile?
Given the part and whole you can use this operation to find the percentage.
What is division?
The third step needed to find the IQR
What is finding the median of the lower and upper?
Stem | Leaf
3 | 4, 5, 6, 6, 9
4 | 2, 5, 7
5 | 3, 8, 9, 9
The median of the above stem-and-leaf plot is this.
What is 43.5?
When a histogram has only one lowest point it can be described as this.
What is skewed?
The first quartile is represented by this vertical line.
What is the left (first) vertical line?
To determine the percentage of a bar graph you must subtract this.
What is the highest percentage listed minus the lowest percentage listed?
