Verified step by step guidance1
Understand that a frequency distribution graph visually represents how often each value or range of values occurs in a dataset.
Recognize that such graphs help in summarizing large datasets by showing the distribution of data points clearly.
Note that frequency distribution graphs do not convert qualitative data into quantitative data; rather, they display the frequency of categories or values as they are.
Acknowledge that these graphs do not guarantee any specific distribution shape, such as normality, nor do they remove outliers from the data.
Conclude that the primary benefit of using frequency distribution graphs is that they make it easier to identify patterns and trends in the data by providing a clear visual summary.
