Researchers from a juice company selected 20
individuals who consented to a taste test. The researchers selected 10
of the 20
individuals at random to be in one group and sent the other 10
individuals to a second group. The individuals in the first group were provided a sample of different juices, where the individuals sipped on plain water after each sample. The second group had the same sample as the first group but were provided with a mixture of baking soda and water between each sample.
Did the researchers use random selection or random assignment for this taste test? Explain.
A) The researchers only used random selection. The individuals who consented to the taste test were not selected at random, but the individuals were randomly selected to be in one of the two groups.
B) The researchers used both random selection and random assignment. The researchers selected the individuals who consented to the taste test at random, and the individuals were randomly selected to be in one of the two groups.
C) The researchers only used random assignment. The individuals who consented to the taste test were not selected at random, but the individuals were randomly selected to be in one of the two groups.
D)The researchers only used random selection. The 20
individuals who consented to the taste test were selected at random, but the individuals were chosen by the researchers to be in one of the two groups.
