Histogram Definition
A histogram is defined as,
A histogram is a type of bar graph that shows the frequency of different ranges of data values in a dataset. It helps to visualize the distribution of the data. Each bar in a histogram represents a range (or “bin”) of values, and the height of the bar shows how many data points fall within that range.
For a histogram,
- Data Range: Entire range of data is divided into smaller, equal-sized intervals, called bins.
- Counting Data Points: Count how many data points fall into each bin.
- Drawing Bars: Draw a bar for each bin. The height of each bar represents the number of data points in that bin.
Example of histogram, consider the following data:
|
Height range (ft.) |
Number of Trees (Frequency) |
|---|---|
|
60 – 65 |
3 |
|
66 – 70 |
3 |
|
71 – 75 |
8 |
|
76 – 80 |
10 |
|
81 – 85 |
5 |
|
86 – 90 |
1 |
(Here, height range is the data range, number of trees( frequency) is the data count and below is the histogram.)
Histogram for above data:
Relative Frequency Histogram
A histogram in mathematics is a graphical representation of data using a bar graph. The height of each bar graph points to the frequency of the data point in a particular range, which makes it easy to visualize the data. They are used in a wide number of fields including statistics, data analysis etc.
In this article, we’ll study about relative frequency histograms.
