Shape of Data Distribution with Graphs

It is useful to describe the shape of data. It can be symmetrical or have a positive or negative skew. Data with a positive skew has a long tail in the positive direction of the horizontal axis. Data with a negative skew has....

• a long tail in the direction of the negative horizontal access

• a long tail in the direction of the positive horizontal access

The data in the picture:

• is negatively skewed

• positively skewed

• symmetrical

Box plots can display the skew of data. The position of the median relative to the quartiles describes the skew. Match the box plots to the correct graphs below

• 
• 

Make notes now on the shapes of distributions and how the mean, median and mode might predict the skew of a distribution. Page 180-181 in the Statistics GCSE book will help. Let me know you have completed this task by writing a message bekow,
