Question
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).

(a) Compare measures of center for the three different samples.
Cooler=_____________
Control=____________
Warmer=____________
 
(b) Calculate the standard deviations for the three different samples. (Round your answers to three decimal places.)
Coolers=_______________
Controls=______________
Warmers=______________
 
Interpret and compare the standard deviations for the three different samples.
___We see from the standard deviations that variability increases as the conditions of the minichambers transition from warmer to cooler.
___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.    
___We see from the standard deviations that there is no difference in variability between the three conditions.
___We see from the standard deviations that variability decreases as the conditions of the minichambers transition from cooler to warmer.
___We see from the standard deviations that variability increases as the conditions of the minichambers transition from cooler to warmer.
 
(c) Do the fourth spreads for the three samples convey the same message as do the standard deviations about relative variability?
____Yes, The fourth spreads do communicate the same message as the standard deviations did.
____No, The fourth spreads do not communicate the same message as the standard deviations did.
