Answer: Third and fifth option
3) The median is the number in the middle on an ordered set of data.
5) To find the middle of an even data set, find the average of the two middle numbers.
Step-by-step explanation:
Given a set of data ordered from lowest to highest, the median of the data is the number that is in the middle. In other words, it is a number x for which it is true that 50% of the data is greater than x and the other 50% of the data is less than x.
For example, for the following set of 7 data:
2, 3, [5], 8, 13
the median is 5.
If the data number is even, for example 10 data:
3, 5, 9, 12, [19, 21], 33, 35, 40, 69
The median is<u><em> the average between the two data that are in the middle </em></u>
Note that the median only represents a partition of the ordered data set. Therefore, it is <em><u>not affected by outlier.</u></em> For example
2, 4, 4.5, 4.8, 5 Median = 4.5
2, 4, 4.5, 67, 1506 Median = 4.5
The median does <u><em>not represent the difference between the highest and the lowest data. </em></u>
Therefore the correct affirmations are:
3) The median is the number in the middle on an ordered set of data.
5) To find the middle of an even data set, find the average of the two middle numbers.
