Question

What is a histogram? And how do iuse it for answers?

Answer 1

A histogram is a type of graph.  It is used to display the range of answers to a question or results from some event.  An example of a histogram is shown below.  I asked 25 people whether they preferred chocolate, vanilla or strawberry ice cream:

C = Chocolate

V = Vanilla

S = Strawberry

C  [][][][][][][][][][][][][]

V  [][][][][][][][]

S  [][][][]

You can also draw a histogram with the various answers or outcomes listed horizontally along the bottom of the page and the count of each answer going up the page.  It was just easier to show how to do it here by listing the answers down the page and the counts going out to the side.
