FAQs On Histogram

For what reason is a histogram most useful?

A histogram is a graphical representation of the frequency distribution of continuous series using rectangles. So, it is good for showing general distribution of given data .

What is obtained from histogram?

Histogram is useful to check the shape of the data distribution. It is used to check whether the process changes from one period to another, to determine whether the output is different when it involves two or more processes. Most importantly to analyse whether the given process meets the customer requirement.

Can a histogram have gaps?

Some histograms have a gap. It occurs between two bars where there are no data provided or the data is 0.

What is a histogram also known as?

Histogram is also known as Frequency distribution. A histogram is a graphical representation in which values are plotted on the horizontal axis, and their density is plotted on the vertical axis.

Who invented the histogram?

Histogram was first introduced by Karl Pearson. It is an approximate representation of the distribution of numerical data.

What is bin in histogram?

The towers or bars of a histogram are called bins. Each bin represents a particular value or data range.

What is bin size in a histogram?

The height of each bin shows how many values from the data fall into that range. Width of each bin = (max value of data – min value of data) / total number of bins. The default value of the number of bins to be created in a histogram is 10.

Histogram is the graphical representation of frequency distribution in Statistics. It is a two dimensional diagram which represents class interval and various frequencies with respect to different class intervals. It is useful to check the shape of the data distribution. It is an important concept in the fields of statistics and mathematics. In this article, we will discuss histogram, its formula, and the solved questions & answers related to it.
