The following figure shows a histogram and corresponding frequency polygon. The data shows the number of victims suffering from a disease 'X' in various months of 2012.
Identify the correct statement(s) among the following.
The following figure shows a histogram and corresponding frequency polygon. The data shows the number of victims suffering from a disease 'X' in various months of 2012.
Identify the correct statement(s) among the following.
The correct options are
A The area under the frequency polygon is equal to the sum of areas of all bars of the histogram.
C June has the highest frequency of victims
From the definition, the area under a frequency polygon is same as the sum of the areas of all the bars of histogram provided the class size of all classes is the same. Hence option A is correct.
Also, we can see that the bar of February is not the smallest. Hence, option B is incorrect.
The bar of June is highest, so option C is correct.
Also, the frequency polygon is correctly drawn joining all the class marks and starting and ending at 0 so option D is not correct.
