What is Frequency Curve?: (A) When the observation is large and group interval is reduced, frequency polygon loses its angulations to become a curve, (B) It is a frequency polygon presenting variation by line, it shows the trend of event over a period of time, (C) It is a graph of cumulative frequency distribution, (D) It is an area diagram of frequency distribution developed over a histogram
Answer is A. Frequency Curve-When the observation is large and group interval is reduced, frequency polygon loses its angulations to become a curve. Line cha/graph-It is a frequency polygon presenting variation by line, it shows the trend of event over a period of time. Cumulative frequency diagram (OGIVE)-It is a graph of cumulative frequency distribution. Frequency Polygon-It is an area diagram of frequency distribution developed over a histogram.
