shape.ftm

shows different types of distributions

 

stat&shape.ftm

investigate relation between shape of distribution of summary statistics

 

scaling.ftm

investigate the change of distribution when transforming a set of numerical data

 

centre1.ftm

centre2.ftm

compare mean and median

 

deviation1.ftm

investigate the spread of a distribution and its standard deviation

 

deviation2.ftm

deviation3.ftm

estimate the number of cases less than one standard deviation away from the mean

 

deviation4.ftm

deviation5.ftm

normal distribution and standard deviation

 

deviation6.ftm

normal distribution and interquartile range

 

percentile.ftm

illustrate the calculation of percentile

 

quartile.ftm

illustrate 5-point summary, box plot and percentile plot

 

StdDev.ftm

Demonstrate calculation of standard deviation and standard scores

 

std_score.ftm

compare distribution of standard scores with the original distribution

 

z_compare.ftm

Use of standard score to compare positions of individual values in two distributions

 

hospital.ftm

Two-way table and Simpsonˇ¦s paradox

 

CorrDemo.ftm

Randomly generated data which shows linear relationship of varying strength and direction in scatter plot and corresponding correlation coefficient.

 

scatter1.ftm

Simply a small collection with two variables and their scatter plot. Vary the pattern by dragging the points around and see how the correlation coefficient is changing accordingly.

 

scatter2.ftm

Detailed study of the correlation coefficient, how it is derived from the standard scores.

 

HypoExams.ftm

3 sets of hypothetical exam scores, showing the importance of identifying outliers and inappropriate grouping.

 

CityTemp.ftm

TV_GPA.ftm

Two more examples of grouping/ lurking variable.
