A frequency distribution is best defined as a table that displays the number of occurrences of each category within a dataset. It systematically organizes data, allowing researchers to see how frequently each value or category appears. This is essential for analyzing data patterns and making informed decisions based on observed frequencies. For instance, if you have a dataset of exam scores divided into categories (such as ranges of scores), a frequency distribution would show how many scores fall into each category. This table provides a clear overview of the distribution of data. In contrast, the other options do not accurately reflect what a frequency distribution is. The first choice relates to statistical calculations rather than data organization. The second option suggests a graphical representation, which is more aligned with histograms or bar charts than a frequency distribution itself. The final choice refers to measures like mean or median, which are about central tendency rather than frequency of occurrences.
