In Class 11, statistics and probability are introduced as important branches of mathematics that deal with the analysis, interpretation, and prediction of data and outcomes. Here’s an overview of what you might study:

1. **Statistics**:
– Data Types: You’ll learn about different types of data, including qualitative (categorical) data and quantitative (numerical) data.
– Data Representation: Methods for representing data, such as frequency tables, histograms, and bar graphs, will be covered.
– Measures of Central Tendency: You’ll study measures like mean, median, and mode, which summarize the central or typical value of a dataset.
– Measures of Dispersion: You’ll learn about measures like range, variance, and standard deviation, which indicate the spread or variability of a dataset.
– Correlation and Regression: These topics deal with the relationship between two variables and how one variable can be used to predict the other.

2. **Probability**:
– Basic Probability: Understanding of fundamental concepts like sample space, events, and the basic rules of probability.
– Conditional Probability: Probability of an event given that another event has occurred.
– Probability Distributions: You’ll study different types of probability distributions, such as the binomial distribution and the normal distribution, and their applications.
– Expected Value: Also known as the mean of a probability distribution, it represents the average value of a random variable.
– Variance and Standard Deviation of a Probability Distribution: Measures of the spread of a probability distribution.

3. **Applications**:
– Real-life applications of statistics and probability in various fields, including economics, biology, sociology, and more.

Understanding statistics and probability is crucial for making informed decisions in many fields and for further studies in mathematics, science, and social sciences.
