## What is back to back stem plot?

A back-to-back stem-and-leaf plot is a method for comparing two data distributions by attaching two sets of ‘leaves’ to the same ‘stem’ in a stem-and-leaf plot. For example, the stem-and-leaf plot below displays the distribution of pulse rates of 19 students before and after gentle exercise.

## How do you make a back to back stem plot in Excel?

Use the following steps to create a stem-and-leaf plot in Excel.

1. Step 1: Enter the data.
2. Step 2: Identify the minimum and maximum values.
3. Step 3: Manually enter the “stems” based on the minimum and maximum values.
4. Step 4: Calculate the “leaves” for the first row.
5. Step 5: Repeat the calculation for each row.

What are Stemplots used for?

A stem and leaf plot, or stem plot, is a technique used to classify either discrete or continuous variables. A stem and leaf plot is used to organize data as they are collected. A stem and leaf plot looks something like a bar graph. Each number in the data is broken down into a stem and a leaf, thus the name.

Why do we use back to back stem and leaf plot?

A back to back stem-and-leaf plot is useful because it allows us to easily visualize the distribution of values in two datasets at the same time and quickly compare two distributions.

### What are the 3 types of stem plots?

Categorical data

• One-way tables.
• Two-way tables.

What is an advantage of Stemplots over histograms?

The Stem-and-leaf plots are similar to histograms, but they reveal the individual values in the display. This is the advantage of stemplots compared with other displays. Since histogram uses grouped data, we miss the individuals in the bins. Like histograms, stemplots can help us analyze data.

What is stem and leaf plot best used for?

## How do stem plots work?

What is the purpose of a stem-and-leaf plot?

### What is a split stem and leaf plot?

A stem and leaf plot is a way to plot data where the data is split into stems (the largest digit) and leaves (the smallest digits). They were widely used before the advent of the personal computer, as they were a fast way to sketch data distributions by hand.
