Statistics - Arithmetic Mean

Statistics – Arithmetic Mean

Arithmetic Imply in the commonest and simply understood measure of central tendency. We are able to outline imply as the worth obtained by dividing the sum of measurements with the variety of measurements contained within the information set and is denoted by the image x¯.

We will talk about strategies to compute the Arithmetic Imply for 3 forms of collection:

Particular person Knowledge Sequence

When information is given on particular person foundation. Following is an instance of particular person collection:

Objects 5 10 20 30 40 50 60 70

Discrete Knowledge Sequence

When information is given alongwith their frequencies. Following is an instance of discrete collection:

Objects 5 10 20 30 40 50 60 70
Frequency 2 5 1 3 12 0 5 7

Steady Knowledge Sequence

When information is given based mostly on ranges alongwith their frequencies. Following is an instance of continous collection:

Objects 0-5 5-10 10-20 20-30 30-40
Frequency 2 5 1 3 12
