Question

what do you meant by histogram,frequency polygon, frequency curve and ogive?​

Answer 1

Answer:

Histogram:a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.

frequency polygon:A frequency polygon is a graph constructed by using lines to join the midpoints of each interval, or bin. The heights of the points represent the frequencies. A frequency polygon can be created from the histogram or by calculating the midpoints of the bins from the frequency distribution table.

frequency curve:A Frequency Curve is a smooth curve which corresponds to the limiting case of a histogram computed for a frequency distribution of a continuous distribution as the number of data points becomes very large.

ogive:1a : a diagonal arch or rib across a Gothic vault. b : a pointed arch. 2 : a graph of a cumulative distribution function or a cumulative frequency distribution.
