Book Description
Excerpt from Integrated Pest Management Research Symposium: The Proceedings; August 1985 Sample unit shape, as well as size, is an important factor to consider when sampling I 0 egg galleries (fig. 2, table The 5 x 20 cm samples have ca. Half the standard deviation as cm samples while the lox 10 cm samples fall in between. The cm (25 cm2) sample unit is just as good as the 20 X5 cm (100 cm?) sample unit even though the latter has four times the bark area. The orientation of the 10 cm sample so that it cuts across more of the vertical egg gallery systems reduces the number of zero counts and the standard deviation. Size of the sample unit still has an effect, but only when com pared between samples of similar shape. Regression equations of sample variance versus mean density can be used to calculate the number of samples needed to estimate I 0 population densities at any desired precision and confidence level. The equation for calculating sample size n is. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
