What can a histogram tell you?

A histogram can tell you several things about a set of data:

  1. Distribution Shape: The histogram shows the distribution of the data and its shape can indicate whether the data is symmetrical, skewed to the right or left, or bi-modal (having two peaks).
  2. Central Tendency: The histogram gives an idea of the central tendency of the data, such as the mean, median, or mode, and how they are affected by outliers.
  3. Spread: The histogram can show how spread out the data is by displaying the range, variance, and standard deviation.
  4. Outliers: Outliers in the data can be identified by unusually large or small bars in the histogram.
  5. Frequency: The height of each bar in the histogram represents the frequency of that particular value in the data set.
