Measure of Central Tendency
Hi,
This is Dr. Sanjeev Kumar Jha, welcome to this channel: "Alpha Plus Education"
I have started a series for SPSS in this series, I will explain several aspects of data analytics in small steps.
So, you are suggested to see all the videos for proper understanding.
About this video:
This video is related to Descriptive Statistics, in this I have explained how to calculate "Measure of Central Tendency" with the help of SPSS.
If data is large enough than we can use software for this purpose. This is Part-2 of Descriptive Statistics, it explains how to calculate Measure of central tendency by SPSS. You can calculate Mean (Average), Median and Mode in just one click.
This SPSS video is very helpful for beginners.

Definition of Measure of Central Tendency
It is a central value of a data set. Furthermore, it is a single value which describes a sample/ population or a complete data set. So, in short, it is summarise a sample/ population by a single typical value.
Measure of Central Tendency includes
1. Mean i.e. average,
2. Mode and
3. Median.
Example of measure of central tendency in day to day life
Suppose, we went to market to buy potatoes (say).We will ask its rate to many sellers. Say rates of five sellers are Rs. 20 per kg, Rs. 22 per kg, Rs. 20 per kg, Rs. 24 per kg, Rs. 19 per kg.
So, average price = Rs. 21 (sum of all price divided by total number of seller)
Mode = Rs. 20 (most occurence of rate)
Median = Rs. 20 (median = total number of data +1 divided by 2 for odd number of data, data is
written in increasing order)
So, you may conclude that Rs. 20 is appropriate price for potatoes.
