1. What is the effect of sample size on the shape of the norma ldistribution?

a) Roll two dice 30 times (like in a boardgame, roll both at the same time). Each time you roll the 2 dice, record the sum of the numbers (e.g., if one dice came up '1' and the second dice came up '5', the sum of the two numbers would be '6'). Record each sum on a frequency distribution (remember: your data, that is the values of the sum, go on the x-axis, while the frequency of obtaining those sums go on the y-axis, i.e., how many times did you get each particular sum value). **if you make a grouped frequency distribution, make sure your intervals are no larger than 5.**

b) Roll the two dice 50 times, recording the sum of the two dice each time and plotting it on a new frequency distribution. **if you make a grouped frequency distribution, make sure your intervals are no larger than 5.**

c) What key difference do you see between the frequency distribution you drew for (a) and the one you drew for (b)?
