Descriptive Statistics* *Check With Your Instructor Before Starting this Intro to Stats (May Be Completed with Chapter 3). Example data set: There are two different soil types, A and B. Six sample measurements were taken of each soil type. Each sample represents how much a 100 mL container of the soil weighed in grams. The balance used is accurate to one-tenth of one gram. MEASUREMENT TYPE SOIL TYPE A SOIL TYPE B Sample 1 35.8 g Sample 2 30.2 g Sample 3 33.3 g Sample 4 34.4 g 30.8 g Sample 5 32.1 g Sample 6 AVERAGE or MEAN STANDARD DEVIATION 1.6 p-value For the following questions you may use a calculator or Excel or another computer program. For direc- tions on how to use Excel, see Chapter 3. 1. Calculate the AVERAGE or MEAN value for soil type A and soil type B and enter the data in the table above. Be sure to use appropriate significant figures. 2. Calculate the STANDARD DEVIATION for soil type A and soil type B and enter the data in the table above. Be sure to use appropriate significant figures. 3. Run a Student's t-test, generate a p-value between two sets of data, and draw a conclusion re- garding significance based on the p-value. 12.2 g 14.9 g 12.2 g 13.6 g 16.8 g 14.3 g 14
