Question

in a test given by 15 student the following marks were awarded find mean, median and mode 52,49,41,38,39,61,58,52,47,72,85,52,62,79,68​

Answer 1

Answer:

mean=816/15

median= 52

mode = 52

detailed steps down below

Step-by-step explanation:

arrange the no in increasing or decreasing order

38,39,41,47,49,52,52,52,58,61,62,68,72,79,85,

mean= $\frac{Sum of observation}{total no of observation}$

      = 52+49+41+38+61+58+52+47+72+85+52+62+79+68/15

     = 816/15

median is the middle tern

when n is odd median is (n+1)/2  ==> 15+1/2 = 8th term=  52

mode = the frequent no = 52

mark me brainliest it helps a lot
