Questions 31-40 Read the experiment below and fill-in-the-blanks with words from the word bank. Dr. K wants to study how the brain responds to different smells. Dr. K sprayed 3 different scents into people's noses, 1-at-a-time. Dr. K measured the people's brain activity with Functional MRI (FMRI). Dr. K's experiment got the following results: 3 Brain activity from 2 Functional MRI 1 0 -1 Scent 1 Scent 2 Scent 3 (31) The scents are the (32) Brain activity is the_ variable of the experiment. variable of the experiment. (33) What type of data is the 3 different scents?_ (34) What type of data is the brain activity as measured by Functional MRI (FMRI)? (35) The boxplot shows data from the experiment. The data distributions for all 3 conditions are positively-skewed (right-tailed). The red dots are which measure of central tendency?_ (36) The boxplot also has blue dots above and below the dotted lines. What are the blue dots? (37) Dr. K wants to test whether the 3 scents elicited different levels of brain activity. Which statistical test should Dr. K run to compare the brain activity for the 3 scents? (38) Dr. K was in the same room as the participants when they did the experiment and also knew exactly which scent they sprayed in the room for the participant. What is this confound called? (39) Since Dr. K was in the same room as the participants, another potential confound is that Dr. K's body odor influenced the brain activity. What is this confound called?
