Normal Distribution and Z Score | Math, Statistics for data science, machine learning

Normal Distribution and Z Score: What is normal distribution or gaussian distribution? These two are terms for the same concept. We will understand normal distribution and Z score in this tutorial. We will also look at use of normal distribution in the field of data science.

"How normal distribution is used in data analysis?" - All I needed was this answer. N it took me 1.5 months to get a proper answer. I got bombarded everywhere with theories no one explained how to use it.. Thanks man. I loved your teaching style. This is the problem, we r using this to solve this problem. Now let's talk about what this is.. this should be the way to teach.

Blown away by how easily you explained such concepts, which I scared me earlier.

Every student deserves a teacher like you and we are all fortunate to learn from you...the way you explain concepts with practical applications is just awesome 👏 Thank you 🙏

[vincentdey]

Your dedication and impact as a teacher deserve global recognition.

[arjunkomarla]

The way you made understood z-score concept by showing the graphic at first and then explaining formula made concept too easy. 👏

[PrashantKumar-mjnb]

You really make complex topics so simple and easy to understand. You are a great mentor 🙏

Learnt for the first time how normal distribution can be used for outlier removal. Thanks so much for explaining the concept and why and how it's used. I like your simple python code to explain the usage of the concept. Great teaching skills!

Was stuck with something similar for past 10 days, u solved it
Hats off guruji

Great content!! thank you!!

If the playlist is in below format it will be more useful.

Descriptive Statistics:

Mean, Median, Mode: Understanding central tendency.
Range, Variance, Standard Deviation: Measuring data dispersion.
Percentiles, Quartiles: Analyzing data distribution.

Inferential Statistics:

Hypothesis Testing: Formulating and testing hypotheses about population parameters based on sample data.
Confidence Intervals: Estimating the range within which a population parameter is likely to fall.
Significance Levels: Understanding and setting significance levels for hypothesis tests.

Probability Distributions:

Normal Distribution: Understanding and working with the normal distribution.
Binomial Distribution: Relevant for analyzing binary outcomes.
Poisson Distribution: Used for counting events over a fixed interval.

Correlation and Causation:
Correlation Coefficient: Measuring the strength and direction of a linear relationship between two variables.
Causation Awareness: Understanding that correlation does not imply causation.
Statistical Tests:
T-Tests: Comparing means of two groups.

Chi-Square Test: Analyzing associations between categorical variables.

ANOVA (Analysis of Variance): Comparing means of more than two groups.

A Great Explanation of this concept, eventhough there are thousands of videos in youtube, this is very unique and clear video for explaining statistics and Standard deviation on data Science... Thanks A Lot !!!!

[learn]

Thank you !
not even professors could take time in explaining concepts in practical way
thanks for your time !

[DeepaDeepa-ybbw]

Excellent first I tried to unstd the nd in Google in many websites couldn't unstd but your video tells inch by inch info about u man

[deepthireddy]

I have watched many videos to understand Z-score in real time data, no one explained this way. I never forget the concept in lifetime. Subscribed the channel and never miss your updates. Hats off to you!

[darshakkumarranpariya]

Sir, you are so good at learning and teaching. Please make video about your learning methods/strategies. 🙏

[debarunkumer]

Love how articulated are the contents. Waiting eagerly for the upcoming videos on this topic.

[Ropit]

Couldn't figure out the use of normal distribution in data analysis.. finally got my answer.. thank you so much

[arunraja]

Thanks for explaining in a simple manner and with a real time example. Got a clear understanding about statistics concepts .

[universal]

I couldn't wait for further videos. How neatly you are explaining 🥳
