Question

for an ungrouped data 10,15,20,25,15,x median and mode are equal then find x and also median from above data?

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
