Do you know how to calculate a z-score? Do you know the characteristics of a standard normal distribution? Do you know how to use the standard normal table to find the shaded area between two z-scores on a curve? Lesson 5: Experimental Design Do you know how to distinguish between the characteristics of experiments and the characteristics of surveys? Do you know what the three primary principles of experimental design are? Do you know what a unit is? Do you know what a subject is? Do you know what a treatment is? Do you know what bias is? Do you know what randomization is? Do you know how to use a random number table to assign subjects to groups? The popping times for popcorn kernels are normally distributed with a mean of 120 seconds and a standard deviation of 18 seconds. The first kernel pops 92 seconds after the microwave oven is started. What is the z-score of this kernel? What is the area between z=-1.4 and z = 0.46? 3 students out of a group of 7 are assigned to a treatment group. +
