Re-randomisation alt text

Diagram has two text boxes of data on the left and three dot plots on the right. 

Left hand text box has two columns, left hand column labelled Age and right hand column labelled Treatment. Each age has a treatment associated with it. Age values 9, 9.5, 9.75, 10, 13, 9.5 are associated with Exercise in the Treatment column. Age values 11, 10, 10, 11.75, 10.5, 15 are associated with Control in the Treatment column.

Right hand text box has one column listing the result of one re-randomisation of the data. It lists the re-randomised treatment only. The list under Treatment is Exercise, Exercise, Control, Control, Control, Control, Control, Exercise, Exercise, Exercise, Control, Exercise.

The top and middle graphs are dot plots with the same horizontal axes, labelled 9 – 15. 

Top pair of dot plots is labelled Data. The Exercise group has six dots at 9, 9.5, 9.5, 9.7, 10 and 13 months. There are six dots for the Control group at 10, 10, 10.5, 11, 11.75 and 15 months. 

Means are marked by purple vertical lines. A red arrow showing the difference between the Exercise and Control means starts from the Exercise mean, 10.05, and ends at the Control mean, 11.3 months. Its length, 1.25 months is written above the arrow.

Middle plot, labelled Re-randomised data, shows the re-randomisation listed in the right hand text box. The Exercise dot plot has dots at 9, 9.5, 10, 10, 11.75, 15. Mean, 10.875, is marked with a purple vertical line. The Control dot plot has dots at 9.5, 9.75, 10, 10.5, 11, 13. The mean, 10.625 is marked with a purple vertical line. A red arrow, showing the negative difference between Exercise and Control, starts from the Exercise mean and ends at the Control mean. The difference is shown by a left pointing arrow. Its value is not written above the arrow. 

The third set of axes, labelled Re-randomisation distribution, is blank.
