Welcome, you're one in 4 million


This article can be used to introduce the investigation of data collected by the Bureau of Statistics (schools may obtain the report mentioned in the article). Students might also be encouraged to carry out their own surveys to see if similar results hold in their locality.

Many of the results in the article are based on percentages and hence claims related to the "average age range for mothers of 25 to 34", the norm of birth weights, and "the average number of children: 2", are "modal" averages. That is each occurs within the most frequently occurring category defined for each variable. "Likely" claims, like finishing high school are based on percentages greater than 50%. Considering the little emphasis placed on mode as a measure of average in the curriculum, it is nice to have some "real world" examples. (See also the article Spending a penny in supermarkets)
