This video takes a look at what Standard Scores are. It's part of the Further Maths 3 and 4 course as part of the Core Module. Building on the previous videos, I take a look at what it means to be a standard (or Z) score. I relate it to Standard Deviations and look at why we need to have Z-Scores. Comparing different scores from different tests is the answer. A few examples of how to we use it to both calculate Z-Scores and to find scores is I know a Z-Score and we can call this video a success.
