Recall that a stem-and-leaf plot is a type of data display that orders numerical data and shows their distribution. Notice that our table does not have values that share the number in the hundred place, so in each row we will have only number.
Let's recall the types of data displays we can use to describe a data set.
Data Display | When Do We Use It? |
---|---|
Pictograph | To show data using pictures |
Dot Plot | To show the number of times each value occurs in a data set |
Stem-and-Leaf Plot | To show how ordered numerical data are distributed |
Box-and-Whisker Plot | To show the variability of a data set by using quartiles |
Circle Graph | To show data as parts of a whole |
Bar Graph | To show frequencies of data values in specific categories |
Histogram | To show frequencies of data values in intervals of the same size |
Line Graph | To show how data change over time |
Scatter Plot | To show the relationship between two data sets using ordered pairs plotted in a coordinate plane |
