Question

for an ungrouped data 10,15,20,25,15,x median and mode equal find x

Answer 1

mode : the term which is repeated often in the data.
mode =15
median=mode =15(given)
mode = 3median-2mean
15=3*15-2mean
15-45=-2mean
-30=-2mean
mean= -30/-2=15
2) mean = (10+15+20+25+15+x)/6
15=(85+x)/6
90=85+x
90-85=x
x=5
