What type of data does a histogram represent?

A histogram is specifically designed to represent the frequency distribution of numerical data. It visually depicts how often each range (or bin) of values appears within a dataset. Each bar in the histogram corresponds to a range of values, and the height of the bar indicates the frequency of data points that fall within that range. This allows for a clear understanding of the distribution, spread, and central tendency of the data.

By focusing on numerical data, a histogram is particularly useful for identifying patterns such as skewness, modality (e.g., unimodal, bimodal), and the presence of outliers. This makes it an invaluable tool in data analysis, particularly when dealing with large datasets where understanding the underlying distribution is crucial for making informed decisions.
