Mathematics Extension 2: 3/4 (people being tutored vs me who doesn't... :<)...
So questions in the 4 unit math paper rarely have new question formats?
For example, a question could be 1+1=2
But a "new" question could be:
Andy has one apple and John has another apple. How much apples do they both have?
To add on to the above post.
Reliability: Make sure that there is nothing wrong with the expierment while doing it.
Validity: Make sure that the controls are kept on.
Oh...
So,
Reliability is to make it overall more consistent even if it is reliability invalid.
Validity just means how can you make it better and more accurate.
Am I correct?
