4,6,7,6,7,6,5,8,3 mean median and mode answer
Answers
Step-by-step explanation:
a) Mean=Total no. of observationssum of the number
⇒ Mean=402+3+4+3+5+5+6+7+8+9+6+6+5+3+13+7+8+8+2+9+11+7+8+4+5+45+48+60+42+53+47+51+54+49+48+47+53+48+44+46
⇒ Mean=40119+770,40889=22.2
∴ Mean=22.2
b) To arrange data in ascending order
Median : 2,2,3,3,3,4,4,5,5,5,5,6,6,6,7,7,7,8,8,8,8,9,9,11,13,42,44,45,46,47,48,48,49,51,53,53,54,60.
Median =28+8=126=8
c)
Mode :- The only number which appears multiple times
Mode =2,3,4,5,
Step-by-step explanation:
mean = sum of all the observations / total number of observations
= 4+6+7+6+7+6+5+8+3 / 9
= 45 / 9
= 5
median = 3,4,5,6,6,6,7,7,8 ( ascending order )
in total of 9 numbers, 5th number is the middle value. 5th number is 6. Therefore 6 is the median.
mode = frequently occuring value
hence, 6 is the mode.
