validity? Polling relies on the principles of inferential statistics‚ which states that we can draw inferences about a set by examining a randomly assembled subset. Random selection is key. 3. How does sample size and margin of error correlate? Margin of error tells us how close to the full population we can expect the sample to take us. They correlate because a sample tells us how many is selected at random from a size of random samples. 4. What factors contribute to an individual’s

This means that the results will be consistent for each group‚ and there is less room for human error. We will use a stopwatch with a resolution of up to 0.001 seconds to ensure that the results are as precise as possible. We will also repeat our investigation three times using the same method and equipment to ensure that it is repeatable and we

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)
