Question

find the median of the collection of first seven whole no. if 9 is also included in the collection. find the difference of the median in two cases. ​

Answer 1

Step-by-step explanation:

0.5

the median of the collection of first seven whole no.

0,1,2,3,4,5,6

median=

=middle most valuable is 4th term

=3

if you add 9

new group is

0,1,2,3,4,5,6,9

mode is average of middle two terms

(3+4) /2

7/2

3.5

Diffrence 3.5-3=0.5

Answer 2

Answer:

The difference in the medians is

= 0.5

Step-by-step explanation:

The first seven whole numbers are 0, 1, 2, 3, 4, 5, 6.

The median is the middlemost value of the data.

Therefore the median of the first seven whole numbers is 3.

If the number nine is added to the set, then the new set of data is

0, 1, 2, 3, 4, 5, 6, 9

The median of new set of data is

$=\frac{3+4}{2}$

= 3.5

The difference in the medians is

$=3.5-3$

= 0.5

Therefore the difference in the medians is 0.5
