Data values vs scores

Sunday, 30 October 2016 | 0 Comments

Note for self really,

In the new NSW Syllabus for Mathematics K-10 what used to be referred to as scores when analysing data are now called data values.

So the definition of mean is written as

$$\bar{x}=\frac{\text{sum of data values}}{\text{number of data values}}$$

There's something nice and tangible about this simple demonstration.

I turned the idea into a animation:

I've added an additional game under the Fractions category on MathsStarters Bingo:

Converting fractions, decimals and percentages

This game focusses on the conversion between the common fractions and their equivalents decimals and percentages. The game is limited to fractions with a denominator of 2, 3, 4, 5, 8 and 10.
