Hello
Can anyone explain to me what normally distributed variation is from the types of variation as I can't seem to understand it very well

So continuous variation of a characteristic shows a continuous range of possibilities between a maximum and minimum value; there are no distinct groups. Examples include height and weight.

If we collect values for a continuous trait for a large number of people, we find that relatively few people will show values close to the extremes of the range - most people show values close to the middle of the range (i.e. the average). This is normal distribution.

If we plot this as a graph, we get a "bell-shaped" normal distribution curve (see attached image - downloaded from internet).
In this graph, the values could be the heights of a large group of people. Most people have a medium height (average values), while relatively few people are at the extremes of the range, i.e. short (lower values) or tall (higher values).

Hope this makes sense!

No problem at all - I remember finding it hard to get my head around at first, but it made sense in the end
