Which term describes a graph showing the frequency of data on a number line?

• A. Line plot
• B. Line graph
• C. Histogram
• D. Pie chart

Answer: (A)

Line plot shows how often each value occurs by placing marks on a number line. Each mark sits above a number on the line, and how many marks are above that number tells you its frequency. That exactly matches a graph showing the frequency of data on a number line. A line graph, on the other hand, connects data points to show trends over time or a continuous variable, not the exact counts at each value. A histogram groups data into ranges with bars, not marks on a number line for each specific value. A pie chart represents parts of a whole as slices, not frequencies along a line. So the line plot is the best fit.
