struggling with my research methods as level psychology h/w question
The question is: If the Mean IQ score is 100, with each Standard deviation being 15, what is the IQ of 68% of population (ie what is the range of possible IQs)
I feel like it could be either really simple and i'm overthinking it, or its more complicated and i haven't figured it out?

If you look at any given normal distribution curve, approximately 68% of the population will fall within 1 SD above and below the mean and approximately 95% of the population will fall within 2 SD above and below the mean.
Does this help?
