A histogram is a way to represent data on a number line. Data values are grouped by ranges. The height of the bar shows how many data values are in that group. This histogram shows there were 10 people who earned 2 or 3 tickets.
Histograms are visual representations of a data set which show how often each value in the data set occurs. The values are grouped into bins along the x-axis. The height of the bar indicates how many values of the data set fall into that bin.
In a histogram, the type of data being measured is represented on the horizontal axis, and the vertical axis represents how many observations are in each bin. Figure 1: The anatomy of a histogram. Histograms are visual representations of a data set which show how often each value in the data set occurs.
Uniform
A histogram is described as “uniform” if every value in a dataset occurs roughly the same number of times Bimodal
A histogram is described as “bimodal” if it has two distinct peaks. We often say that this type of distribution has multiple modes – that is Multimodal
A histogram is described as “multimodal” if it has more than two distinct peaks. Related: What is a Multimodal Distribution Left Skewed
A histogram is left skewed if it has a “tail” on the left side of the distribution. Sometimes this type of distribution is also called “negatively” skewed Right Skewed
A histogram is right skewed if it has a “tail” on the right side of the distribution. Sometimes this type of distribution is also called “positively” skewed Random
The shape of a distribution can be described as “random” if there is no clear pattern in the data at all Additional Resources
The following tutorials provide more information on how to describe distributions. Left Skewed vs A histogram is a
plot that lets you discover, and show, the underlying frequency distribution (shape) of a set of continuous data. This allows the inspection of the data for its underlying distribution (e.g., normal distribution), outliers, skewness, etc.In statistics, a histogram is a
graphical representation of the distribution of data. The histogram is represented by a set of rectangles, adjacent to each other, where each bar represent a kind of data. Statistics is a stream of mathematics that is applied in various fields.A histogram is
used to summarize discrete or continuous data. In other words, it provides a visual interpretation of numerical data by showing the number of data points that fall within a specified range of values (called “bins”). It is similar to a vertical bar graph.
Key Takeaways
- A histogram is a visual presentation used to summarize discrete or continuous data.
- One uses bars of various heights to show the data in a graphical form called the histogram graph. ...

- Skewness Skewness is the measure of the asymmetry of a histogram (frequency distribution ). A histogram with normal distribution is symmetrical. ...
