1. Look at the properties of the normal curve and sharethe proportion (or percentage) of scores that fall between one standard deviation below the mean and one standard deviation above the mean?
2. Now look at it again and sharethe proportion (or percentage)of scores that fall between two standard deviations below the mean and two standard deviations above the mean?
3. How much does the proportion/percentage change under the curve from the one standard deviation distance to the two standard deviation distance?
4. In your own words, describe the people whose scores fall in the center of the curve, where do they stand in relation to the mean and to each other. Are they similar to one another in the variable being measured?
5. Now think about the people whose scores fall in the tails of the curve. What can you say about their scores in relation to people's scores in the center of the distribution? Do you think they are similar to most people in the distribution, or are they different when it comes to the variable measured?
