L24 Quiz_ Group Meeting_ Biostatistics (Complete Answered & Explained)
Students in an Introductory Statistics class at BYU-Idaho were studying prices of cold cereal at grocery stores in Rexburg. To get a sample of cold cereal prices, they went to Albertson's and rolled a die to decide which box from the left of the top shelf they would start on. They then recorded every 6th cereal after the first, moving from left to right down the shelves, recording the name, size, and price of each cereal in their sample. Is this study an experiment or an observational study, and why? An observational study, because the students had no control over which cereals were selected. An observational study, because the students had no control over the price of the individual cereals.
