After examining over one million online restaurant reviews and the associated weather conditions, Bakhshi, Kanuparthy, and Gilbert (2014) reported significantly higher ratings during moderate weather compared to very hot or very cold conditions. To verify this result, a researcher collected a sample of n = 25 reviews of local restaurants during an unusually hot period during July and August and obtained an average rating of M = 7.29. The complete set of reviews during the previous year averaged μ = 7.52 with a standard deviation of σ = 0.60.
