4.10 DESCRIBING A FREQUENCY DISTRIBUTION
Answers
Answer:
frequency distribution is an overview of all distinct values in some variable and the number of times they occur.That is, a frequency distribution tells how frequencies are distributed over values.
Frequency distributions are mostly used for summarizing categorical variables. That's because metric variables tend to have many distinct values. These result in huge tables and charts that don't give insight into your data. In this case, histograms are the way to go as they visualize frequencies for intervals of values rather than each distinct value.
Anyway. Let's look at some examples of frequency distributions.

Frequency Distribution
What Is Frequency Distribution?
A frequency distribution is a representation, either in a graphical or tabular format, that displays the number of observations within a given interval. The interval size depends on the data being analyzed and the goals of the analyst. The intervals must be mutually exclusive and exhaustive. Frequency distributions are typically used within a statistical context. Generally, frequency distribution can be associated with the charting of a normal distribution.
KEY TAKEAWAYS
Frequency distribution in statistics is a representation that displays the number of observations within a given interval.
The representation of a frequency distribution can be graphical or tabular so that it is easier to understand.
Frequency distributions are particularly useful for normal distributions, which show the observations of probabilities divided among standard deviations.
In finance, traders use frequency distributions to take note of price action and identify trends.
