+
+# 2 | Data Structure & Algorithms
+Data Structure is the most important thing to learn not only for data scientists but for all the people working in computer science. With data structure, you get an internal understanding of the working of everything in software.
+
+Understand these topics
+
+- Types of Algorithm Analysis
+- Asymptotic Notation, Big-O, Omega, Theta
+- Stacks
+- Queues
+- Linked List
+- Trees
+- Graphs
+- Sorting
+- Searching
+- Hashing
+
+
+# 3 | Pandas Numpy Matplotlib
+Python supports n-dimensional arrays with Numpy. For data in 2-dimensions, Pandas is the best library for analysis. You can use other tools but tools have drag-and-drop features and have limitations. Pandas can be customized as per the need as we can code depending upon the real-life problem.
+
+### Numpy
+- Vectors, Matrix
+- Operations on Matrix
+- Mean, Variance, and Standard Deviation
+- Reshaping Arrays
+- Transpose and Determinant of Matrix
+- Diagonal Operations, Trace
+- Add, Subtract, Multiply, Dot, and Cross Product.
+
+### Pandas
+- Series and DataFrames
+- Slicing, Rows, and Columns
+- Operations on DataFrame
+- Different ways to create DataFrame
+- Read, Write Operations with CSV files
+- Handling Missing values, replace values, and Regular Expression
+- GroupBy and Concatenation
+
+
+### Matplotlib
+- Graph Basics
+- Format Strings in Plots
+- Label Parameters, Legend
+- Bar Chart, Pie Chart, Histogram, Scatter Plot
+
+
+# 4 | Statistics
+
+### Descriptive Statistics
+- Measure of Frequency and Central Tendency
+- Measure of Dispersion
+- Probability Distribution
+- Gaussian Normal Distribution
+- Skewness and Kurtosis
+- Regression Analysis
+- Continuous and Discrete Functions
+- Goodness of Fit
+- Normality Test
+- ANOVA
+- Homoscedasticity
+- Linear and Non-Linear Relationship with Regression
+

+- One way ANOVA
+- Two way ANOVA
+- Chi-Square Test
+- Implementation of continuous and categorical data
+
+
+# 5 | Machine Learning
+The best way to master machine learning algorithms is to work with the Scikit-Learn framework. Scikit-Learn contains predefined algorithms and you can work with them just by generating the object of the class. These are the algorithm you must know including the types of Supervised and Unsupervised Machine Learning:
+
+- Linear Regression
+- Logistic Regression
+- Decision Tree
