Data analysis – How does the weight of a baby change?
In 2009 a new chart on baby growth was introduced. These new charts are based on the advice that babies should be breast fed for 6 months and then supplemented with food for another 6 months. The older charts were based on formula-fed babies. This could mean that more children in the last few years will be classified as overweight.
The newspaper report of this event can be found at:
The two charts are shown below:

Please complete the table below (Choices about the babies’ mass and their ages now have been completed for boys ‘A’, ‘B’ and ‘C’. You can decide on your own for boys ‘D’ and ‘E’) You could also make your own table for the girls.

Activity 3
Please write various statements about the babies that they have created, relating it to both of the growth charts. For example, ‘If boy ‘A’ was 2 Kg when he was born, then, according to both growth charts, he would probably be overweight if he was 11Kg when he was a year old.’
What statements can you create based on the data?
