the following frequency distribution table shows The distance travelled by some Rickshaw In day. Observe the table and answer the question! 1. What is the modal class? 2. which is the median class and why? 3.write the cumulative frequency of the class preeceding the median class? 4.what is the class Interval h to calculate median?
Answers
Step-by-step explanation:
i.
Modal Class is defined as the class where the frequency is maximum or highest.
From above data highest frequency is 82.
So the modal class is 74.5 to 79.5.
ii.
Median of the frequencies is = middle of Sum of frequencies
= (10 + 34 + 58 + 82 + 10 + 6 ) / 2
= 200 / 6 = 100
Median class is defined as the class where the median frequency falls in the cumulative frequency.
100 frequency comes in class 69.5 to 74.5
Hence Median class is 69.5 to 74.5
iii.
Cumulative frequency of the class preceding the median class.
Median class preceding the median is 64.5 to 69.5.
Hence frequency of that class is 44.
iv.
Class interval = range of the class element set = 64.5 - 59.5 = 5.
Class interval = 5
