Question

Draw a ‘more than ogive curve’ for The Following Data:

\begin{tabular}{|l|l|} \hline CLASS & FREQUENCY \\ \hline \hline \( 0-10 \) & 5 \\ \( 10-20 \) & 9 \\ \( 20-30 \) & 10 \\ \( 30-40 \) & 12 \\ \( 40-50 \) & 8 \\ \( 50-60 \) & 7 \\ \( 60-70 \) & 5 \\ \( 70-80 \) & 4 \\ \hline \end{tabular}

Answer 1

The given data is:

For constructing the ogive curve, First the given frequency must be converted into a more than cumulative frequency distribution as follows:

Plot the points $(0,60),(10,55),(20,46),(30,36),(40,24),(50,16),(60,9),(70,4)$ on the graph by taking the lower boundary of the class on the $x-axis$ and cumulative frequency on the $y-axis$.

Then join these points to make the Ogive curve.

Thus, The required more than Ogive curve for the given data is created.
