In order to draw a frequency polygon by using a histogram, which of th...
Explanation:
To draw a frequency polygon using a histogram, we need to follow certain steps. Let's go through each statement and determine which one is incorrect:
a) Obtain the mid-points of three class-intervals of the highest frequency on the Y-axis, one adjacent to the first on its right and one adjacent to the last, on its left.
This statement is incorrect. Instead of obtaining the mid-points of three class-intervals, we should obtain the mid-points of all the class-intervals. The mid-points represent the x-coordinates for plotting the frequency polygon.
b) Obtain the frequency distribution and draw a histogram representing it.
This statement is correct. Before drawing a frequency polygon, we need to obtain the frequency distribution and represent it using a histogram. The histogram helps us visualize the distribution of data.
c) Join these mid-points of the adjacent rectangles of the histogram by a dotted line.
This statement is correct. After obtaining the mid-points of all the class-intervals, we join these points using dotted lines to create the frequency polygon. Each mid-point represents the center of a rectangle in the histogram.
d) Obtain the mid-points of the upper horizontal side of each rectangle.
This statement is incorrect. Instead of obtaining the mid-points of the upper horizontal side of each rectangle, we should obtain the mid-points of the lower horizontal side of each rectangle. These mid-points represent the x-coordinates for plotting the frequency polygon.
Conclusion:
The incorrect statement is option 'A' which states that we should obtain the mid-points of three class-intervals of the highest frequency. Instead, we should obtain the mid-points of all the class-intervals.
