A million random digits with 100,000 normal deviates. Glencoe, IL: Free Press. Doing random selection. To begin, you need to identify some larger population, such as, say, the 30 students enrolled in a psychology class. You want to draw a sample of 5 students from the group of 30-how do you do it? (The following procedure can be contracted for a smaller sample or expanded for a larger one-the logic is the same.) 2aIIprEIT0 \\is<0 pEIa Itylthl(a<

Basic Experimental Design 91 Shut your eyes and, using the index finger of your dominant hand, place it anyplace on Table 4.3. My finger ended up in column 4 out of the 10 containing random digits, on a string of numbers in row 00115 (see Table 4.3). The string of numbers is 05339. By reading across, I can treat each pair of digits as two-digit numbers for 05 and 33, followed by the single digit 9. Since we are using double, not single, digits, we can join 9 to the first number in the adjacent string to its right (i.e., 15470), which is 1, for 91. This number is followed by 54 and 70. We now have five numbers, but since our sample only has 30 names in it, so far we can only select one name (corresponding to the fifth person). We need to continue moving across the columns in the random numbers in Table 4.3 until we select four other numbers between 01 and 30 (excluding 5, of course). If you follow this process, you will obtain the numbers 22, 19, 12, and 18 (this last number was found by linking the last digit (i.e., 1) in row 00115 to the first digit in row 00116 in the first column of random digits (i.e., 8). Assuming the list of 30 students in the psychology class is in alphabetical order, you would select the names corresponding to the 5th, 22nd, 19th, 12th, and 18th place (a nonalphabetized list, such as a seating chart, could also be used). We now have our sample of five people.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
