2. Central Tendency
The central tendency is one of the most quintessential concepts in statistics. It is
defined as
“Central tendency is a descriptive summary of a dataset through a single
value that reflects the center of the data distribution. Along with the variability
(dispersion) of a dataset.”
3. Types of Central Tendency
The types of central tendency are givern below
Mean
Median
Mode
4. Mean
In simple words Represents the sum of all values in a dataset divided by the
total number of the values.
OR
Mean of a set of numbers is the sum of the numbers divided by the number of
items in the list.
For example:3, 5, 6,1, 2, 7
Solution
mean=3+5+6+1+2+7/6
mean=24/6
mean=4
5. Median
The median is the middle number in a data set. To find the median, list your data
points in ascending order and then find the middle number.
For example:23, 24, 26, 26, 28, 29, 30, 31, 33
Solution
here the middle number in this set is 28 because there are 4 numbers below it
and 4 numbers above.
6. Mode
The mode is the most common number in a set.
For example: 21, 21, 21, 23, 24, 26, 26, 28, 29, 30, 31, 33
Solution
As we know that it is most common no
so The mode in this set of numbers is “21”
