The most feasible method is to ask other U.S. schools to help with cluster sampling. On a smaller scale, you could mimic this by cluster sampling from grocery stores in the area. The easiest choice (but least reliable) is convenience sampling. Pursue the idea of cluster sampling with other schools. To do this, you simply modify random selection techniques to choose your schools. Following are two ways to use random numbers for selection. Method 1: Random Number Tables Such tables can be found on the Internet by typing number tables” in the “random search box. Here is an example of what you might get: 241983 724152 579108 492124 912127 508114 280505 344304 298477 911677 859342 730503 184740 934279 233161 887766 847111 724875 393074 591162 996737 358072 852052 761457 330180 678434 267867 657965 812675 230136 276862 466559 711671 103110 259433 112082 050556 058988 273557 154354 533800 188724 706462 730447 481964 913634 627872 459415 564428 022187 445787 920698 352175 172443 463765 576652 981420 452204 121938 693647 353129 156861 696173 707475 If you have 100 schools and wish to select 12 of them to help with the study, you assign each school a number between 00 and 99. Then read the table from left to right and select the schools as their numbers appear. The 12 schools are Nos. 24, 19, 83, 72, 41, 52, 57, 91, 8, 49, 21, and 27. If you have 1,000 schools on the list, number them from 000 to 999 and read the three digits at a time. What are the first five schools in this sample? To using the same numbers for every study, you can start from a different row. If you read three digits at a time starting with the third row, what five schools do you put in your sample?
