Answer 1

mean =median, so the data is symmetrical

Explanation:

Given

Data set= {10,5,8,10,12,6,8,10,15,6,12,18}

Mean= Sum of data points/number of data points

= (10+5+8+10+12+6+8+10+15+6+12+18)/12

=10

Median= mid value

={5,6,6,8,8,10,10,10,12,12,15,18}

Middle values are 10 and 10

Median = 10+10/2

= 20/2

= 10

Mean= median so there will be no skewness and the distribution is equal !
