Solution
Data visualization represents data as graphs or charts so patterns, trends, and insights are easier to see than in a table of numbers.
Descriptive statistics such as the mean, median, mode, variance, and standard deviation summarize a dataset. A histogram shows how scores are distributed around those measures. A boxplot displays the median, quartiles, and outliers. A bar chart or line graph makes averages and trends easier to compare. Visualization therefore turns the same summary numbers into a form that is quicker to interpret.
