How do you visualize numeric data?

One good way of visualizing the distribution of a numerical variable is a histogram. In a histogram, data are binned into intervals and heights of the bars represent the number of cases that fall into each interval. Provides a view of the data density. Especially useful for describing the shape of the distribution.

How do you visualize data with many variables?

Another way of visualizing multivariate data for multiple attributes together is to use parallel coordinates. Basically, in this visualization as depicted above, points are represented as connected line segments. Each vertical line represents one data attribute.

How do you visualize data distribution?

A histogram is the most commonly used plot type for visualizing distribution. It shows the frequency of values in data by grouping it into equal-sized intervals or classes (so-called bins). In such a way, it gives you an idea about the approximate probability distribution of your quantitative data.
