Step-by-step explanation:
Finding the median
median is regarded as the middle number of a data set.
steps to follow to find median :
Step 1
place the data set in ascending order:
45,18,27,26,32,28,47,30,35
= 18 ,26,27 ,28, 30, 32 ,35 ,45,47
Step 2.
what is the total number of values in the data set and is it even or odd?
the total number of values are 9
this means its an odd data set
Step 3
median of an odd data set has the following formula:
= number of data values + 1 / 2
= (9 + 1 ) / 2
= 10/2
=5th position
the 5th value in the data set is 30
median is 30
