The Central Board of Secondary Education had developed a new elective course for the class 12 Commerce stream i.e. Applied Maths. Inferential Statistics is one of the topics in the Class 12 Applied Maths syllabus. This post takes you through detailed information about CBSE Class 12 Applied Maths Inferential Statistics.
Inferential statistics is the process of using data analysis to understand the properties of an underlying distribution of probability. It takes data from a sample and makes inferences about the larger population from which the sample was drawn.
CBSE Class 12 Applied Maths Inferential Statistics curriculum consists of data-based case studies from the field of business, economics, psychology, biology, and census data is used to appreciate the power of data in contemporary society.

Descriptive Statistics is used to describe a given set of data whereas inferential statistics are used to analyze collected data. The introduction of the former i.e. descriptive Statistics will be discussed in the 11th standard, while the latter inferential statistics will be discussed in detail in the CBSE 12 Applied Mathematics Syllabus.
Inferential statistics takes data from a sample population and makes inferences about the larger population from which the sample was drawn.
For example, one may ask a sample of 50 random people in a mall about their shopping experience and formulate a bar chart (descriptive statistics) and use that research to make predictions about major population visiting malls (Inferential statistics). Inferential Statistics is very important for the interpretation and statistical models of prediction.

Inferential statistics is used in almost every branch of fields like social sciences, actuarial sciences, computer sciences, economics, business, medicine, demographic shifts, etc, or wherever we need to analyze a given set of data.
You can understand the importance of Inferential statistics by reviewing these daily life problems which are solved using inferential Inferential statistics concepts.
To help you get an idea about the type of questions that will be asked from the inferential statistics topic, we have provided few sample questions here.
Q) Suppose X1, . . . , X100 are i.i.d random variables which have uniform distribution on [a − 2, a + 2], where a is unknown. Suppose the random sample produces a sample mean equal to 3.
Compute a 95% confidence interval for a.
Q) In a mythical national survey, 225 students are randomly selected from those taking calculus and asked if calculus is their favorite subject. 100 students reply that calculus is their favorite subject. Give a 95% confidence interval for the proportion of all students taking calculus who consider it their favorite subject.
Q) Suppose in a random sample of 225 undergraduate men at UMD that the average best (highest weight) bench press is 150 pounds, with a sample standard deviation of 20 pounds. Compute a 95% confidence interval for the average best bench press for UMD undergraduate men.
