Final Answer :
B
Explanation :
A frequency polygon is a graph that displays the frequencies of scores within a class interval as a continuous line. Option A (standard deviation) is a measure of variability, not a graph. Option C (histogram) displays the frequencies of scores as bars, not a continuous line. Option D (frequency distribution) refers to the organization of raw data into intervals along with their respective frequencies, not a graph.
