![]() ![]() Normal distribution-A bell-shaped curve used to compare data to a normal distribution. ![]() The following descriptive statistics are calculated and displayed as lines on histograms: You can change the color of a histogram's bins using the color patch next to Bin color. Changing the number of bins allows you to see more or less detail in the structure of your data. You can adjust this by changing the Bins value on the Data tab. Square root transformations can only be applied to numbers greater than or equal to zero. Transformations can be either logarithmic or square root. You can apply transformations to the chart using the With transformation parameter. When the data is skewed (the distribution is lopsided), you can transform the data to make it normal. Some analytical methods require that data be normally distributed. Histograms require one continuous Number variable on the x-axis. The Data tab configurations include the variable that is used to create a histogram, the number of bins, and the statistics that are displayed on the chart. The histogram below visualizes distribution of voter turnout in the 2016 United States election. Understanding the distribution of your data is an important step in the data exploration process. For each bin, a bar is drawn where the width of the bar represents the range of the bin, and the height of the bar represents the number of data points that fall into that range. ![]() The x-axis in a histogram is a number line that has been split into number ranges, or bins. Histograms visually summarize the distribution of a continuous numeric variable by measuring the frequency at which certain values appear in the dataset. ![]()
