Unit 2.2
Descriptive Statistics
Central Tendency
- Measures of central tendency for ungrouped and grouped data – arithmetic mean, geometric mean, harmonic mean, median, and mode – Composite measures; Comparison of different measures, Quartiles, Deciles, and Percentiles
- Index numbers – Price Index Numbers – problems of construction, methods of construction – aggregative (simple and weighted) and averaging price-relatives (simple and weighted), Laspayre’s, Paasche’s index numbers, Fisher’s Index Number, Quantity Index Numbers, Tests of Index Numbers, Fixed Base and Chain Base, Wholesale price index, and cost of living index, Uses of index numbers
Dispersion
- Absolute measures of dispersion for ungrouped and grouped data – range, quartile deviation, mean deviation, standard deviation – Composite SD; Comparison of different measures
- Relative measures – coefficient of variation, coefficient of mean deviation, coefficient of quartile deviation
- Distribution of income and wealth – Lorenz curve, Gini Coefficient, Theil’s Index
Skewness and Kurtosis
Skewness and Kurtosis
- Moments – central and non-central – computation, conversion
- Measures of skewness – Bowley’s measure, coefficient of quartile deviation, measure based on moments
- Measure of kurtosis – measure based on moments
Bivariate Analysis
Bivariate Analysis
- Bivariate data – scatter diagram, Simple correlation coefficient – computation, limitations, and properties
- Simple linear regression – Least squares technique – Properties
Learning Objectives
- Understand the Basics of Statistics: To introduce students to the fundamental concepts of statistics, including the collection, presentation, and analysis of data.
- Data Handling Techniques: To teach students how to gather data from primary and secondary sources and methods to compare them.
- Variable Classification: Students will learn to classify variables into discrete, continuous, and categorical types.
- Graphical and Tabular Representation: Students will gain the ability to present data using textual, tabular, and diagrammatic methods such as frequency distributions, histograms, and ogives.
- Basic Analysis Techniques: Students will learn how to perform univariate and bivariate data analysis.
Learning Outcomes
- Proficiency in Data Collection Methods: By the end of the course, students will have an understanding of primary and secondary data collection techniques and their relative advantages and disadvantages.
- Ability to Classify Variables: Students will be able to differentiate between discrete, continuous, and categorical variables, and use this classification in statistical analysis.
- Competency in Data Presentation: Students will be able to present data using various formats including textual, tabular, and diagrammatic approaches like frequency polygons and histograms.
- Basic Analytical Skills: Students will be proficient in analyzing data sets using univariate and bivariate techniques, and will be able to interpret the results.

Student Reviews
I like EduSure particularly because of how well organised their content on the portal was, their videos on all the topics were excellent, and I could access everything at my convenience. What helped me the most where the short notes for every chapter, which helped me revise quickly.
Even though the classes can be online, you can ask your doubts and they will always respond. Ma'am and Sir are extremely nice teachers, they helped me understand so many concepts and helped us plan and strategise these exams.
I feel very fortunate to have Samkith Sir and Mahima Ma'am as our teachers because I feel that without their consistent efforts and sincere commitments I wouldn't have been able to crack ISI's entrance exam and also IIT JAM. Cracking these entrance exams will be a lot lot easier with EduSure.
" I never had to look for any other guidance- EduSure books & Student Portal were more than sufficient. I blindly followed Samkith Sir's advice to practice DSE 15 years, 5 times "
" I used to give regular Mock Tests organised by EduSure team along with full attendance in their doubt sessions. "
" Watching the solution videos from the portal and practicing past year question papers for 4 to 5 times got me into ISI "
" The Student Portal and all the other resources provided by EduSure was very handy and helped a lot "
“ Mahima ma’am (DSE) and Ankit sir (ISI) had carefully strategized the way to target these exams. ”
" Not a self study person- EduSure classes helped me a lot "
