STATISTICS FOR DATA ANALYTICS - 1
Material which I have taken to learn ➖
Vlearn ( Statistics) implementation in Excel .
Krish Naik ( live playlist - statistics) implementation in Python.
Paid course ( Intelliphat - Advanced in Business Analytics) implementation in Python.
Paid course ( Data Science - pw skills) implementation in Python.
Books ➖
An Introduction to Statistical Learning: With Python
Whatever I will learn in this course will be shared as per my experience.
A branch of applied mathematics that involves the collection, organising,description, presentation, analysis and interpretation of numerical data.
TYPE OF STATISTICS ➖
DESCRIPTIVE STATISTICS
INFERENTIAL STATISTICS
Descriptive statistics :- It describes the property of the dataset.
Inferential statistics :- To get results from the dataset ( it uses a dataset to get the result.)
TYPE OF DATA ➖
QUANTITATIVE DATA
QUALITATIVE DATA
LEVEL OF MEASUREMENT ( scale of measurement )
Nominal scale data.
Ordinal scale data.
Interval scale data.
Ratio scale data.
DESCRIPTIVE STATISTICS
BASIC :-
SUMMARISING
ORGANISING.
Based on Variable ➖
Univariate - Everything about that variable
One variable
Ex :- mean, median , mode.
BiVariate -
Two variable
Ex :- Scatter plot
MultiVariate -
More than One variable
Ex:- Heat map
Types of Descriptive Statistics :-
Measure of Frequency
Grouped Frequency
Ungrouped Frequency
Measure of Central Tendency
Mean, Median, Mode
Measure of Dispersion or Variation
Variance
Range,
Standard & Absolute Deviation
Coefficients of Variation
Measure of Position
Percentile & Quartile
Measure of Shape
Skewness
Kurtosis
Box & Whisker Plot
Common terms :-
Population :- complete dataset is called population.
Sample :- it is a dataset which has resemblance of the population in a small proportion which can be used for Analytics.
These functions are fundamental for various tasks in Excel, including text manipulation, logical operations, conditional formatting, and data analysis.
