Ungrouped Frequency Distribution: This type lists individual data values along with their corresponding frequencies. It’s useful for small datasets where each value can be easily counted.

Grouped Frequency Distribution: In this type, data values are organized into intervals or "bins." Each interval contains a range of values, and the frequency represents how many observations fall within that range. This is particularly helpful for larger datasets.

Cumulative Frequency Distribution: This type accumulates frequencies over a range of intervals. It shows the total number of observations that fall below or at the upper limit of each interval, helping to understand the distribution of data.

Relative Frequency Distribution: This type expresses frequencies as proportions or percentages of the total number of observations, allowing for easy comparison between different categories.
