Students' Learning Outcomes
After completing this unit, the students will be able to:
- Construct cumulative frequency table and cumulative frequency polygon or Ogive.
- Interpret the median, quartiles, deciles, percentiles and inter quartile range from cumulative frequency curve.
- Interpret and analyze box and whisker plots.
- Construct and interpret data from scatter diagrams and also draw lines of best fit.
- Measure correlation using scatter diagram.
- Calculate the range, standard deviation and variance for grouped data.
- Use the mean and standard deviation to compare two sets of data.
- Solve real life situations involving variance and standard deviation for grouped data.
- Apply concepts from measures of dispersion to solve real life situations (determining the consistency of data, checking variability in forecasting, manufacturing, finance and economics).
