Mean and median of number 10,12,12,15,15,17,18,18,18,and19
Answers
Answer:
add all the frequencies and divide by no of frequencies than we will get mean of the data.To find median no of frequencies by 2.
Step-by-step explanation:
10+12+12+15+15+17+18+18+18+19=154
154÷10=15.4 (mean)
median 10/2=5th observation (i.e 15)
Answer:
Mean is 19.4
Median is 16
Step-by-step explanation:
The mean is computed as:
Mean = Sum of all numbers / Total Numbers
= (10 + 12 + 12 + 15 + 15 + 17 + 18 + 18 + 18 + 19) / 10
= 194 / 10
= 19.4
The median is computed as:
Median = (n + 1) / 2
where n is total number which is 10
As the total number are 10, which is even. We will find middle term as:
= 10 + 1 / 2
= 5.5
From 5.5 we cannot conclude the middle term. It is somewhere between 5th and 6th term. So, it is computed as:
= 5th term + 6th term / 2
= 15 + 17 / 2
= 32/ 2
= 16
