In a press conference, EMA's CEO, Mr Khoo Chin Hean said that the scope for savings is high considering that power consumption patterns show that 40 per cent of households, from one-room flats to landed properties, use more than the monthly average.
I had a "Ah Ba Then" moment.
I normally don't have the penchant for saying dialects in my blog, but the English language fails to express the "wah lao - even aunties know that" kind of feeling when you read that sentence.
From what highly-trained Maths teachers in the Singapore education had taught me, "average" is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.
So, assuming all Singapore families save 50% on their electricity bills, a family in the "high user" category would still remain a "high user" as the average bill would have fallen, but there would be "scope for savings ... considering that power consumption patterns show that 40 per cent of households, from one-room flats to landed properties, use more than the monthly average", right?
Mathematically speaking, we can't reduce the percentage of families that are above the average, can we?
Any Maths teachers care to comment?
