TY - CHAP M1 - Book, Section TI - Chapter 8. How to Test for Trends A1 - Glantz, Stanton A. Y1 - 2012 N1 - T2 - Primer of Biostatistics, 7e AB - The first statistical problem we posed in this book, in connection with Figure 1-2A, dealt with a drug that was thought to be a diuretic, but that experiment cannot be analyzed using our existing procedures. In it, we selected different people and gave them different doses of the diuretic, then measured their urine output. The people who received larger doses produced more urine. The statistical question is whether the resulting pattern of points relating urine production to drug dose provided sufficient evidence to conclude that the drug increased urine production in proportion to drug dose. This chapter develops the tools for analyzing such experiments. We will estimate how much one variable increases (or decreases) on the average as another variable changes with a regression line and quantifies the strength of the association with a correlation coefficient.* SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/03/28 UR - accessbiomedicalscience.mhmedical.com/content.aspx?aid=57415527 ER -
