2. Histogram Histogram is a graph of adjacent rectangles on the . A  histogram  is an alternative way to display the distribution of frequency. A histogram is a plot that lets you discover, and show, the frequency distribution.   Histogram X-axis Frequency

3. Why we use histograms? Histograms are particularly useful for large data sets.  it provides a  visual interpretation  of numerical data by showing the number of data points. Histograms can display a large amount of data and the  frequency  of the data values. The  median and distribution of the data can be determined by a histogram

4. General view:

5. TYPES: HISTOGRAM CONSTRUCTIONS IN OF TWO TYPES:

6. Histogram for Continuous Frequency, Continuous Frequency is like: Create histogram: Draw . Frequency must be . Label the using suitable scale. Make a bar graph by using given data.  

7. Histogram for Continuous Frequency,

8. Histogram for Non-continuous Frequency Non-Continuous Frequency is like: Create histogram: As the adjacent rectangles cannot be made because of non-continuous frequency. Thus, we will make a proportional height. By dividing the frequency by class interval. Let make a table.

9. Ages boundaries Class interval frequency Proportional height Ages boundaries Class interval frequency Proportional height

10. Histogram for Non-continuous Frequency

11. Histogram distribution A histogram may have any shape. It all depends upon your data. So, don’t worry about your graph.
