How do you find the median number in maths?
The median is the 'middle' of a set of numbers. Sort the list and find the middle number. If the set contains an even number of items, then take the middle two numbers and take the average of those two.
What is the process of finding the total number of items when two or more groups of items are joined is called?
addition
How do you work out the median of a group?
Sort the data items into numerical order (ascending is usual, but descending can be used). The median is the number in the middle: If there are an odd number of items in the dataset, then the median is the middle number, which is the (n+1)/2th item (where n is the number of items in the dataset). Otherwise there is an even number of items in the dataset and the median is the mean of the two in the middle. These items are the n/2th and the (n/2 + 1)th items.
What is the median of 20 and 40?
When there is an even number of items in the data set the median is the mean average of the middle two. The middle two are the two items themselves, namely 20 and 40, so the median is (20 + 40)/2 = 30.
What is the median when 19 and 20 are in the middle?
Whenever there are an even number of items in your data set, the algebraic mean of the 2 middle numbers is the median. So in this case 19.5
What is the median of 2 20 19 15 11 9 7 1?
sorted: 1 2 7 9 11 15 19 20 number of items: 8 middle items: 9 and 11 average of middle items, or median: (9+11)/2 = 10
What are the opitical discs that store items by using microscopic indentations and the flat areas that are in the middle layer of the disc are called what?
dents

Is median always sometimes or never in a data set?
If the sample has an odd number of items in it then the median will definitely be in the sample at least once because the median is value of the set of data items whose value(s) are in the middle of the sample when the sample is sorted from smallest to largest. If the sample has an even number of items in it then if the middle items are different the median will be their average, and it will differ from all of the items in the data set. I could continue in this vein but already you can see that the median sometimes occurs in a data set but not always.
In Serial position effect items least likely to be remembered?
Items least likely to be remembered are the items in the middle. Unless the items in the middle are extremely odd.The Serial Position Effect is the theory that we are more likely to remember the items at the start or end of a list.
Why does the number above the fraction bar is called numerator?
It "enumerates" the portion of items being discussed.
