Understand the concept of a frequency distribution: it is a way to organize data by showing each unique data value alongside the number of times it appears in the dataset.
Recognize that a frequency distribution is typically presented in a table format where one column lists the distinct data values and another column lists their corresponding frequencies (counts).
Compare the given options to this definition: a graph showing relationships between two variables is a scatterplot, not a frequency distribution.
A summary of mean and standard deviation provides measures of central tendency and spread, but does not show frequencies of individual data values.
A list of all possible outcomes of a random experiment is a sample space, which is different from a frequency distribution that summarizes observed data.
