Sampling Methods Mean Yield Per Plot (kg) Estimate of Total Yield (kg) Convenience (farmer's) (6+7+2+9+4+5+5+8+7+7)/10 6 x 100 = 600 6 Simple random (38+92+9+15+91+60+61+76+80 52.2 x 100 = 5220 +86) / 10 = 52.2 Horizontal strata (2+5+44+51+62+76+81+82+86+ 50.2 x 100 = 5020 99) / 10 = 50.2 Vertical strata (6+28+16+39+44+51+61+75+ 49.8 x 100 = 4980 86+92) / 10 = 49.8 Answer these questions:- 1. Four different methods of choosing plots are compared. Is there a reason, other than convenience to choose one specific method over another? 2. How did your estimates differ according to the diverse sampling methods used? 3. Compare your result to someone else in the class. Is it similar? 4. Pool the results of all students for the mean yields from the simple random samples and make a class box plot. Repeat for means from horizontal and vertical strata too. Evaluate the class box plots for each sampling method. What do you observe? 5. Which sampling method should you use? Why
