Question

For an ungrouped data 10,15,20,25,15,x median and mode are equal.find x and also mean for the givendata

Answer 1

most repeated term in the data is mode
mode =15
Given
median=mode=15
from empharical formula the relation between mode, median and mean is
mode =3median-2mean
15=3×15-2mean
15-45=-2mean
-30=-2mean
-30/-2=mean
mean=15
2) mean =(sum of the observations)/(number of observations)
15=(10+15+20+25+15+x)/6
90=85+x
90-85=x
x=5

Answer 2

To solve this problem we must know the following-
i)  Mode is the value with highest frequency. In data set there could be more than one mode.
ii) Median is the value of the middle term when the data are arranged in ascending order. A data set can have only one median.
