Question

Find mean,median,mode 2,5,9,0,1,5,5,5,7,6

Answer 1

Answer:

Mean = 4.5

Median = 5

Mode = 5

Step-by-step explanation:

Firstly arranging the given data in ascending order we get;

  0, 1, 2, 5, 5, 5, 5, 6, 7, 9    Number of observations = 10

Mean of data is given by =  $\frac{Sum of all values}{n}$ = $\frac{0+ 1+ 2+ 5+5+ 5+ 5+ 6+ 7+ 9}{10}$ = 4.5 .

Median of above data;

Here the number of observation is even i.e. n = 10

So, the formula is given by = $\frac{(\frac{n}{2})th + (\frac{n}{2} +1)th }{2}$ obs. = $\frac{5th + 6th}{2}$ = $\frac{5+5}{2}$ = 5

Hence, median is 5.

Now, Mode = Number appearing maximum times in the data which 5 i.e. 4 times.

Therefore mode of data = 5 .
