A study like that described in the previous question was actually conducted. The statistician William Gossett (who used the name Student when he devised the t-test, discussed in later chapters), described how instead of randomly allocating 20,000 pupils into conditions, the researchers could have just used a couple of dozen pairs of monozygotic (identical) twins, randomly allocating one in each pair to each condition. This is called a:
A) matched-pairs design.
B) Latin squares design.
C) between-subjects design.
D) cross-sectional design.
