Data science, Machine Learning and Artificial intelligence market is on boom.
Data science is basically converting structured or unstructured data in to insight, understanding and knowledge using scientific methods, processes and algorithms.

R is free open source language used as statistical and visualization software. It can deal with structured (organised) and semi-structured (semi-organised) data.

To learn R for data science we covered all aspects as follows:

✤ Introduction
✤ Data-Types in R
✤ Variables in R
✤ Operators in R
✤ Conditional Statements
✤ Loop statements
✤ Loop Control Statements
✤ R Script
✤ R Functions
✤ Custom Function
✤ Data Structures
⁎ Atomic vectors
⁎ Matrix
⁎ Arrays
⁎ Factors
⁎ Data Frames
⁎ List
✤ Import/Export Data – Assign values to data structure
✤ Data Manipulation/Transformation
✤ Apply function of Base R
✤ dplyr Package

Statistics is crucial part to start learning in in this field.
Terms used in statistics is very strange and hard to understand for beginners, so we tried our best to explain these terms in very easy language for Novice, Intermediate or Advanced level guys in Data Science, Machine Learning, AI field.
Here we covered so many terms used in statistics like -
✽ Hypotheses
✽ Quantitative methods
✽ Qualitative methods
✽ Independent and Dependent variables
✽ Predictor and Outcome variables
✽ Categorical variables
✽ Binary variable
✽ Nominal variable
✽ Ordinal variable
✽ Continuous variable
✽ Interval variable
✽ Ratio variable
✽ Discrete variable
✽ Confounding variables
✽ Measurement error
✽ Validity and Reliability
✽ Two methods of data collection
✽ Types of variation
✽ Unsystematic variation
✽ Systematic variation
✽ Frequency distribution
✽ The Mean
✽ The Median
✽ The Mode
✽ Dispersion in distribution of Data
✽ Range
✽ Interquartile range
✽ Quartiles
✽ Probability
✽ Standard deviation
