I found that many students as well as parents are scared of statistics. As we know histograms is a part of statistics. More over histograms is not frequently studied by students still it is used in wide range of fields. You can say that it is a part of collection of science. Basically histograms is an area diagram. The general mathematical definition of histograms is known as two dimensional frequency density diagram. There are generally 5 types of histograms depending on distributions.

There are some steps which need to follow while constructing a histograms.

Always keep that in mind the histogram is different from bar graph. Bar graph is one dimensional and histogram is two dimensional.

Understanding

There are some steps which need to follow while constructing a histograms.

**1)**Take x-axis and y-axis and mark x-axis as class intervals and y-axis as frequencies.**2)**If class intervals are given in inclusive form then convert to the exclusive form Because class intervals can not be in inclusive form.**3)**Now draw rectangles between class intervals base and corresponding heights of frequencies.**4)**As we know the class intervals are on x-axis and frequencies are on y-axis the rectangles will be constructed on each class interval.**5)**The height of rectangle is proportional to corresponding frequency if the intervals are equal.**6)**The area of rectangle is proportional to corresponding frequency if the intervals are unequal.Always keep that in mind the histogram is different from bar graph. Bar graph is one dimensional and histogram is two dimensional.

Understanding

**Histogram**is step by step method. Hope the above basic concepts of histogram helps you.
