Question

Which normal distribution has a wider​ spread: the one with mean 1 1 and standard deviation 7 7 or the one with mean 7 7 and standard deviation 1 1​?

Answer 1

Spread refers to variance, so a wider spread means more variability and a larger standard deviation.

This also means the graph of the distribution curve will be wider and more spread out.

Therefore, the distribution with mean of 11 and std dev of 77 has the wider spread.
