2. 2. Categorical Data Categorical data refers to the classification of data into various categories such as race, gender, language, nationality etc. Numerical Data Numerical data are the ones which are expressed in terms of numbers. Types of Data Datamites Data Science Courses
3. 3. Probability Distribution Functions Probability talks about the likeliness of the occurrence and non-occurrence of an event. A probability function helps in describing the distribution of a random variable and is denoted as pf. For example, the probability function of X can be denoted as pX: R→[0,1] Datamites Data Science Courses
4. 4. Measures of Variability Standard Deviation Square root of variance is known as Standard deviation. Its shows the amount of deviation from the mean value. Variance It is obtained by taking the average of squared the deviation. Range It is the difference between two values, one being the maximum and the other minimum in a dataset.

5. 5. Measures of Variability ➔ Adjusted Square ➔ It is the modified version of the R square.It is adjusted based on the number of predictors in the model. ➔ Z- Score ➔ It refers to the distance of the mean from the data points. It is the number of standard deviations from the mean. A Z score might include 3 or more standard deviations. ➔ R Squared ➔ It explains the quantity of variation of a dependent variable, with the help of an independent variable.

Correlation ranges from -1 to 1. Basically, it talks about how well two data is related to each other. Covariance It is the measurement of relationship between two random variables. In other words it measures the variance between two variables. Datamites Data Science Courses
