There are different steps involved in this process, and it will be further explained in the rest of this article.

Some other methods that require calculation include a histogram, which needs a class interval and a pie chart that requires one to calculate the degree of each slice in the pie.Ĭomputations are no doubt a common occurrence in statistical analysis, but minimal when visualizing data.
