# How to Find the Mode of a Histogram (With Example)

The mode of a dataset represents the value that occurs most often.

To find the mode in a histogram, we can use the following steps:

1. Identify the tallest bar.

2. Draw a line from the left corner of the tallest bar to the left corner of the bar immediately after it.

3. Draw a line from the right corner of the tallest bar to the right corner of the bar immediately before it.

4. Identify the point where the two lines intersect. Then draw a line straight down to the x-axis. The point where the line hits the x-axis is our best estimate for the mode.

The following step-by-step example shows how to find the mode of the following histogram: ## Step 1: Identify the Tallest Bar

First, we need to identify the tallest bar in the histogram.

This is the bar with the bin range of 16 to 20: ## Step 2: Draw the First Line

Next, we need to draw a line from the left corner of the tallest bar to the left corner of the bar immediately after it: ## Step 3: Draw the Second Line

Next, we need to draw a line from the right corner of the tallest bar to the right corner of the bar immediately before it: ## Step 4: Identify the Point of Intersection

Next, we need to identify the point where the two lines intersect. Then draw a line straight down to the x-axis: The point where the line hits the x-axis is our best estimate for the mode.

In this example, our best estimate for the mode is roughly 17.

Note: Since the data in a histogram is grouped into bins, it’s not possible to know the exact value of the mode but the method that we used here allows us to make our best estimate.
