Mathematics is a commonly studied subject by the students pursuing higher studies in the field of Economics, Commerce, and social science, but the current CBSE mathematics elective subject was meant for science subjects relating to various problems of physical science. Having this in mind, CBSE has decided to add a new academic elective to the curriculum of Sr. Secondary classes with an aim to provide students relevant experience in Mathematics which can be used in the fields other than Physical Sciences. Applied Mathematics can be opted by the interested students from the academic year 2020-21.

  • Applied Mathematics will help students reinforce the logical reasoning skills of formulating and validating mathematical arguments.
  • The course content consists of various important topics like inferential mathematics which can be used to describe and analyze a given set of data.
  • 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.
  • The inferential statistics unit holds a weightage of six marks in the CBSE Applied Mathematics theory exam.
  • Inferential statistics 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

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. 

  • Weather prediction models are developed using statistics that equate past weather conditions with current weather conditions in order to predict future weather conditions.
  • Stock market analysis is done using computational models of inferential statistics, Stock analysts get the information about the economy using statistics concepts.
  • Retailers keep track of everything they sell and to know the stock using statistics. Worldwide leading retailers use inferential statistics to analyze present sales and forecast future demands.
  • Each large organization uses business statistics and utilizes various data analysis tools.

CBSE Class 12 Applied Maths Inferential Statistics Study Material PDF

Inferential statistics is an easy and scoring topic if studied with the correct approach and methodology. Candidates can refer to some of the below-mentioned preparation tips to become more confident, and successful in inferential statistics.

  • Develop an effective and time-efficient schedule for practicing problems regularly.
  • Go through with the conceptual meaning of the definition and then start practicing questions of statistics.
  • Before starting questions on Inferential statistics brush up on the fundamentals of descriptive statistics as some of its concepts will be used in the questions.
  • Attempt solved examples and then solve the exercise questions to evaluate your knowledge about the concept.
  • After studying all the subjects according to the latest syllabus and exam pattern, start your evaluation during which you need to solve the CBSE Sample Papers.

Inferential statistics Applications

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.

Candidates can understand the importance of Inferential statistics by reviewing these daily life problems which are solved using inferential Inferential statistics concepts.

  • A laboratory blood test is 99% effective in detecting a certain disease when it is in fact, present. However, the test also yields a false-positive result for 0.5% of the healthy person tested (i.e. if a healthy person is tested, then, with probability 0.005, the test will imply he has the disease). If 0.1 percent of the population actually has the disease, what is the probability that a person has the disease given that his test result is positive?
  • In a national survey, 500 students are randomly selected from those taking applied maths and asked if applied maths is their favorite subject. 100 students reply that applied maths is their favorite subject. Give a 90% confidence interval for the proportion of all students taking applied maths who consider it their favorite subject.
  • 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.
