(a) Compare measures of center for the three different samples. Cooler x~= Control x~= Warmer x~= (b) Calculate the standard deviations for the three different samples. (Round your answers to three decimal places.) Cooler s= Control s= Warmer s= 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 ( CC ).
