OGIVE is constructed using
A
Third quartile range
B
Semi-quartile range
C
Cummulative frequency table
D
Inter-quartile table
medium Difficulty
Verified Correct Answer: Option C
Step-by-Step Mathematical Solution
An ogive is constructed using the cumulative frequencies from a frequency distribution table.
Collect Data: Organize your data into a frequency distribution table.
Calculate Cumulative Frequency: Add frequencies cumulatively for each class interval.
Determine Class Boundaries: Identify the upper boundaries of the class intervals.
Plot Points: Plot cumulative frequencies against the upper class boundaries.
Draw the Ogive: Connect the points with a smooth curve, starting from (0, 0).
Label the Axes: Clearly label the x-axis (upper boundaries) and y-axis (cumulative frequency).
