Types of Graphs
One way to visualize data. Every data point is shown as a dot above its value on a number line.
Dot Plot
The difference between the maximum and minimum.
Range
The smallest value in a data set.
Minimun
A distribution that has two peaks.
Bimodal
The average for a set of numbers.
Mean
One way to visualize quantitative data that groups data into bins.
Histograms
This measures how far values are from the mean.
Standard Deviation
The largest value in a data set.
Maximum
A data distribution that has a vertical line of symmetry.
Symmetric
The middle number when data is in order.
Median
It divides data into four sections using five values.
Box Plot
The distance between Q1 and Q3.
Interquartile Range
Data values that are far away from most others.
Ouliers
A distribution where bars are about the same height
Uniform
What is the Median for this set of data?
2, 5, 7, 11, 14, 15
9
Dot plots are best to use when graphing what size data sets?
Small
Standard Deviation
Which data set shows more variability?
A. 4, 5, 6, 7, 8
B. 2, 5, 8, 11, 14
C. 6, 6, 6, 6, 6
B
The intervals used to group data values in a histogram
Bins
A data distribution where there are more values concentrated on one end of the data, and few values on the other end.
Skewed
Calculate the mean for this data?
4, 5, 6, 7, 8
6
It's best to use these type of graphs to plot large sets of data.
Histograms and Box Plots
This group of numbers includes the min, Q1, median, Q3, and max.
The Five Number Summary
These divide a data set into four equal parts.
Quartiles
A data distribution of data at the center and fewer points farther from the center.
Bell-Shaped
This measure is NOT affected as much by outliers.
Median
