What is Normalization | Min-Max Normalization, Z-score Normalization, Decimal Scaling Normalization

Normalization definition in Data Mining and all important points are explained here in English. Min-Max Normalization, Z-score Normalization, Decimal Scaling Normalization in English is explained with examples in this video of CSE concepts with Parinita Hajra

[@rrahulrroyr]

You teach in such a way that the topic can be understood very easily ... Please carry on !!

[@CSEconceptswithParinita]

Thank you so much for motivating :)

[@saicharan4081]

Simply superb. I understood the topic is very easy.

[@CSEconceptswithParinita]

My pleasure 😊

[@rohitsai4995]

standard deviation formula denominator is N not N-1

[@CSEconceptswithParinita]

No

[@anshu261]

Is it n of n-1?

[@alaamohammed7402]

The explanation is amazing and very clear thank you ♥

[@annmaryjoseph684]

If there is a decimal number, how do we select j in case of decimal scaling? ex: 10.25,8,10,12.1

[@figuredoutfitness8154]

Can we do z score normalization with having min n max value too?

[@nitindube3694]

How to normalize when only two data set are given means only two value how to get min and max in this case

[@Enterprise-Architect]

In Z-score method, value for 8 is -0.97 which does not fit between 0 and 1... Is it correct representation?

[@hackein9435]

Good work!

Thanks for acknowledging!

Can we pick any values to be normalized?

your are awosome

[@kanny8742]

why n-1 for standard deviation??

[@akshraj25]

Range =(-115) to 75
value =(-60)
2 nd value =15
new range = (-25) to 25
I have tried with these number it did not work could you please help me to normalize these values .I was trying to do it in excel .
More over your explanation is great i was very comfortable to understand the topic.

[@Sam-up1rg]

Very Hepful

[@CSEconceptswithParinita]

Keep learning, keep supporting ✌😊

[@justinpatel8751]

what if the new value to be normalized goes beyond the range as an example 98001, then what do we handle that in min-max normalization?

[@adeirvan7474]

just change the max(A) to 98001 instead of 98000

[@ujjwalkarnani1059]

Great video but small correction the denominator in standard deviation formula will be n instead of n-1 right?

[@anshu261]

Are you sure it is n and not n-1?

[@viswes3844]

@@anshu261 yes it's n

[@khaleabhishek5023]

Both will do

[@figuredoutfitness8154]

Ma'am I have a query

[@ananthkumarchakka8230]

Suppose that a hospital tested the age and body fat data for 18
randomly selected adults with the following results:
age 23 23 27 27 39 41 47 49 50
%fat 9.5 26.5 7.8 17.8 31.4 25.9 27.4 27.2 31.2
age 52 54 54 56 57 58 58 60 61
%fat 34.6 42.5 28.8 33.4 30.2 34.1 32.9 41.2 35.7
(i) Normalize the two attributes based on z-score normalization.
(ii) Calculate the correlation coefficient (Pearson’s product
moment coefficient). Are these two attributes positively or
negatively correlated? Compute their covariance.
