CHAPTER 5 Choosing the type of probability sampling What you will learn in this chapter: •• •• •• •• •• •• The types of probability sampling and how they differ from each other Steps in carrying out the major probability sample designs The strengths and weaknesses of the various types of probability sampling Differences between stratified sampling and quota sampling Differences between stratified sampling and cluster sampling Differences between multistage cluster sampling and multiphase sampling

doing so‚ we can correct systematic errors caused by the burette’s or glassware’s tolerance values. Theory1: Volumetric glassware is used to accurately measure volumes. In any given experiment‚ students may come across systematic errors or random errors. Random errors are not able to be corrected by a standard mean because they are not consistent. However‚ systematic errors are consistent and is able to be detected which allows students to correct the error that was found. So‚ using uncalibrated

mistakes can happen. In the health care field errors can be deadly and are taken very seriously. There are several basic components of EHR and allows for patient information to be shared and charted throughout their life. The three basic components that will talk about concerning the EHR is patient management component‚ clinical component‚ and laboratory components and how they affect different safety measures. Proper documentation allows for less errors to happen. To ensure accurate documentation

Aim To find out difference in the heat of combustion for different types of alcohols. Hypothesis The higher the number of carbon atoms in an alcohol is‚ the higher the energy for the heat of combustion. Alcohol is a homologous series‚ a series of organic compounds with similar formula and chemical properties‚ and increase in molecular size and mass. When the equations for combustion of these alcohols are listed in the order of increasing number of carbon atoms‚ Methanol 1 CH3OH(l) + 3/2 O2(g)

Furthermore‚ this experiment tested a mathematical model for the value of gravity that that makes use of the small-angle approximation and the proportional relationship between the square of the period of oscillations to the length of the pendulum.Sources of error for this procedure included precision in both length and time measurement tools‚ reaction time of the stopwatch
