Grouped Frequency Histogram

Grouped Frequency Histogram Grouped Frequency Histogram A Graphical representation which shows the distribution of data items is known as histogram. With the help of histogram we can show any information about the data. Rectangle shape is used to show the frequency of data item in successive intervals in grouped Frequency Histogram. The variables which are Independent are plotted along the horizontal axis and the variables which are dependent are plotted along the vertical axis. The height of grouped frequency histogram is equals to the height of Rectangle. Now we will see how to draw a grouped frequency histogram: For designing the grouped frequency histogram we need to follow some steps shown below: Know More About Graphs of Circular Functions

Step1: First we take some data for the histogram. Step2: We plot a graph according to the given data for the histogram and we know that the variables which are independent are plotted along the horizontal axis and the variables which are dependent are plotted along vertical axis. Suppose we have 1 item in between 5 to 6, and 2 items are in between 6 - 7 and 3 item is in between 7 to 8, 5 items are in between 8 to 9, 6 item in between 9 to 10, 4 items between 10 to 11 and 6 items between 11 to 12. For making a histogram graph we have to follow all the above steps: Step1: First we select the data item i.e. We have 1 item in between 5 to 6, and 2 items are in between 6 - 7 and 3 items is in between 7 to 8, 5 items are in between 8 to 9, 6 items between 9 to 10, 4 item between 10 to 11 and 6 item between 11 to 12. A histogram is constructed from a frequency table, thus its name "frequency histogram". The intervals from the table are placed on the x-axis and the values needed for the frequencies are represented on the y-axis. The frequencies are depicted by the height of a rectangular bar located directly above the corresponding interval. The shapes of histograms may vary by changing the size of the intervals.

Some textbooks differentiate between histograms and bar graphs. In their definitions, a bar graph differs from a histogram in that the rectangular bars in a bar graph are separated from each other by a small gap. In histograms, the bars touch each other. The cumulative frequency is the running total of the frequencies. On a graph, it can be represented by a cumulative frequency polygon. The graph will look like a bar graph that shows the data after it has been added from the smallest interval to the largest interval.
