# Histogram Maker

**
Instructions
**
: The following graphical tool creates a histogram based on the data you provide in the boxes below. All you have to do is type your data and also the number of bins (typically between 4 and 10). The tool will construct a histogram for you, corresponding to the data you entered.

## More About Histograms

What is a histogram? A histogram is a specific type of bar char that takes data from a scale variable, uses groups to categorize possible ranges of values, and it provides the frequency of values in the range, for data set passed. A histogram is an excellent visual tool to get a first glance perspective of the distribution properties of a random variable (especially if the same size of data collected is sufficiently large).

There are variations that can be used for drawing a histogram. Sometimes the y-axis represents frequencies, and other times it represents relative frequencies (percentages), but regardless of the option, the shape will the same (provided that the same bins are used for the X-axis).

Also, many software packages like SPSS or Minitab will be able to fit known distribution on top of a histogram to see how well the shape of the distribution fits the shape of the expected distribution.

### Using the Histogram of Assess the distribution of the underlying variable

Constructing a histogram, among other things, allows you to get a quick glance of the shape of the distribution we are dealing with. When the histogram has a bell-shape type of shape, we suspect that the distribution may be normal.

Assessing normality from the histogram itself could be tricky. It is much better to use a normality test, like this Anderson-Darling test calculator .
