Figure 5
The figure shows three box plots. The box plot on the top left is labeled “a,” and the details for the box plot are as follows. The horizontal axis is labeled “Operative temperature,” and the markings from left to right are: “17 degrees Celsius to 19.9 degrees Celsius,” “18 degrees Celsius,” “23 degrees Celsius to 25.9 degrees Celsius,” “24 degrees Celsius,” “29 degrees Celsius to 31.9 degrees Celsius,” and “30 degrees Celsius.” The vertical axis on the left is labeled “Thermal sensation” and ranges from negative 5 to 4 in increments of 1 unit. On the right side of the vertical axis, each marking is labeled from top to bottom as follows: “4” is “very hot,” “3” is “hot,” “2” is “warm,” “1” is “slightly warm,” “0” is “neutral,” “negative 1” is “slightly cool,” “negative 2” is “cool,” “negative 3” is “cold,” and “negative 4” is “very cold.” Each marking on the horizontal axis has one box plot. For each operative temperature, the red box plot represents “R E,” and the blue box plot represents “I V E.” The details for the box plot are as follows: 17 degrees Celsius to 19.9 degrees Celsius: R E: Minimum: NIL. Lower Quartile: 1. Median: 1.5. Upper Quartile: 2. Maximum: Nil. 18 degrees Celsius: I V E: Minimum: negative 2. Lower Quartile: negative 1. Median: negative 0.8. Upper Quartile: 0. Maximum: 1. Four outliers are present horizontally between the “Maximum” of “17 degrees Celsius to 19.9 degrees Celsius,” and “18 degrees Celsius.” 23 degrees Celsius to 25.9 degrees Celsius: R E: Minimum: 0. Lower Quartile: 1. Median: 1.5. Upper Quartile: 2. Maximum: 3. 24 degrees Celsius: I V E: Minimum: 0. Lower Quartile: 0.3. Median: 0.9. Upper Quartile: 1. Maximum: 2. 29 degrees Celsius to 31.9 degrees Celsius: R E: Minimum: 2. Lower Quartile: 2.3. Median: 2.3. Upper Quartile: 2.3. Maximum: 3. 30 degrees Celsius: I V E: Minimum: NIL. Lower Quartile: 2. Median: 2.5. Upper Quartile: 3. Maximum: 4. One outlier is present between the “Maximum” of “23 degrees Celsius to 25.9 degrees Celsius” and “24 degrees Celsius.” The box plot on the top right is labeled “b,” and the details for the box plot are as follows. The horizontal axis is labeled “Operative temperature,” and the markings from left to right are: “17 degrees Celsius to 19.9 degrees Celsius,” “18 degrees Celsius,” “23 degrees Celsius to 25.9 degrees Celsius,” “24 degrees Celsius,” “29 degrees Celsius to 31.9 degrees Celsius,” and “30 degrees Celsius.” The vertical axis on the left is labeled “Thermal comfort” and ranges from negative 1.0 to 1.5 in increments of 1 unit. On the right side of the vertical axis, some markings are labeled from top to bottom as follows: “1.0” is “warm discomfort,” “0.0” is “comfortable,” and “negative 1.0” is “cold discomfort.” Each marking on the horizontal axis has one box plot. For each operative temperature, the red box plot represents “R E,” and the blue box plot represents “I V E.” The details for the box plot are as follows: 17 degrees Celsius to 19.9 degrees Celsius: R E: Minimum: NIL. Lower Quartile: 0.0. Median: negative 0.25. Upper Quartile: 0.75. Maximum: 1.0. 18 degrees Celsius: I V E: Minimum: 0.0. Lower Quartile: 0.0. Median: negative 0.0. Upper Quartile: 0.0. Maximum: 0.0. 23 degrees Celsius to 25.9 degrees Celsius: R E: Minimum: NIL. Lower Quartile: 0.0. Median: 0.4. Upper Quartile: 1.0. Maximum: NIL. 24 degrees Celsius: I V E: Minimum: 0.0. Lower Quartile: 0.1. Median: 0.1. Upper Quartile: 0.1. Maximum: 1.0. 29 degrees Celsius to 31.9 degrees Celsius: R E: Minimum: 0.0. Lower Quartile: 0.75. Median: 0.75. Upper Quartile: 0.75. Maximum: 1.0. 30 degrees Celsius: I V E: Minimum: 0.0. Lower Quartile: 0.9. Median: 0.9. Upper Quartile: 0.9. Maximum: 1.0. The box plot on the bottom center is labeled “c,” and the details for the box plot are as follows. The horizontal axis is labeled “Operative temperature,” and the markings from left to right are: “17 degrees Celsius to 19.9 degrees Celsius,” “18 degrees Celsius,” “23 degrees Celsius to 25.9 degrees Celsius,” “24 degrees Celsius,” “29 degrees Celsius to 31.9 degrees Celsius,” and “30 degrees Celsius.” The vertical axis on the left is labeled “Thermal preferences” and ranges from negative 1.5 to 1.5 in increments of 1 unit. On the right side of the vertical axis, some markings are labeled from top to bottom as follows: “1.0” is “warmer,” “0.0” is “no change,” and “negative 1.0” is “cooler.” Each marking on the horizontal axis has one box plot. For each operative temperature, the red box plot represents “R E,” and the blue box plot represents “I V E.” The details for the box plot are as follows: 17 degrees Celsius to 19.9 degrees Celsius: R E: Minimum: NIL. Lower Quartile: negative 1.0. Median: negative 0.0. Upper Quartile: 0.4. Maximum: 1.0. 18 degrees Celsius: I V E: Minimum: negative 1.0. Lower Quartile: 0.0. Median: 0.0. Upper Quartile: 0.0.

Lower Quartile: 1.0. Median: negative 0.4. Upper Quartile: 0.0. Maximum: NIL. One outlier is present between the “Maximum” of “23 degrees Celsius to 25.9 degrees Celsius” and “24 degrees Celsius.” 29 degrees Celsius to 31.9 degrees Celsius: R E: Minimum: negative 1.0. Lower Quartile: negative 1.0. Median: negative 1.0. Upper Quartile: negative 1.0. Maximum: negative 1.0. 30 degrees Celsius: I V E: Minimum: negative 1.0. Lower Quartile: negative 1.0. Median: negative 1.0. Upper Quartile: negative 1.0. Maximum: negative 1.0.
