An article described an experiment in which observations on various characteristics were made using minichambers of three different types: (1) cooler (PVC frames covered with shade cloth), (2) control (PVC frames only), and (3) warmer (PVC frames covered with plastic). One of the article's authors kindly supplied the accompanying data on the difference between air and soil temperatures (°C).

Cooler Control Warmer (b) Calculate the standard deviations for the three different samples. (Round your answers to three decimal places.) Cooler Control Warmer S = Interpret and compare the standard deviations for the three different samples. O we see from the standard deviations that variability increases as the conditions of the minichambers transition from warmer to cooler. O we see from the standard deviations that variability increases as the conditions of the minichambers transition from cooler to warmer. O we see from the standard deviations that variability increases when the conditions of of the mini-chambers transitions from the cooler to the control and decreases when the conditions transition from the control to warmer. O we see from the standard deviations that variability decreases as the conditions of the minichambers transition from cooler to warmer. O we see from the standard deviations that there is no difference in variability between the three conditions.
