DATA ANALYSIS LAB
The course will enable the students to
- Understand the role of statistics in data analysis.
- Apply statistical techniques to research data for analyzing and interpreting data carefully.
Course Outcomes (COs):
Learning Outcome (at course level) | Learning and teaching strategies | Assessment Strategies |
|---|---|---|
CO 79 Use statistical tool for analyzing and interpreting data. CO 80 Effectively use statistical software to perform statistical computations and display numerical and graphical summaries of data sets. CO 81 Compute and interpret the coefficient of correlation and the "line of best fit" for bivariate data. CO 82 Model and analyze measurement data using the appropriate distribution, e.g. normal, binomial, chi-square. CO 83 Perform sensitivity analysis on data. | Approach in teaching: Interactive Lectures, Discussion, Tutorials, Reading assignments, Demonstration, Team teaching
Learning activities for the students: Self-learning assignments, Effective questions, Simulation, Seminar presentation, Giving tasks. | Class test, Semester end examinations, Quiz, Solving problems in tutorials, Assignments, Presentation, Individual and group projects |
Note: Students should be given hands-on experiences to use appropriate software packages for selected statistical analysis.
The following test should be performed using appropriate software packages
- Formation of frequency distribution table (inclusive and exclusive)
- Graphical representation- histogram, frequency polygon, ogives
- Measures of Central Tendency- Mean, Median and Mode
- absolute and relative Measures of Dispersion- range, Quartile Deviation, Mean Deviation, Standard Deviation
- Coefficient of correlation- karl pearson and spearmens rank
- Fitting of Regression lines and prediction.
- Normal Distribution-area under the curve
- Chi-square tests- Goodness of fit, Independence of Attributes 2x2 and RXC contingency tables, testing of single variance
- Application of Student’s t-test for small samples- test of significance of single mean, difference in means, independent and paired T test.
- F-test for two sample variances.
- Analysis of Variance- one-way classification, two-way classification
