Rumsey You can test for an average difference using the paired t-test when the variable is numerical (for example, income, cholesterol level, or miles per gallon) and the individuals in the statistical sample are either paired up in some way according to relevant variables such as age or perhaps weight, http://www.dummies.com/education/math/statistics/how-to-test-for-an-average-difference-using-the-paired-t-test/ or the same people are used twice (for example, using a pre-test and post-test). Paired tests are typically used for studies in which someone is testing to see whether a new treatment, technique, or method works better than an existing method, without having to worry about other factors about the subjects that may influence the results. With the average difference, you match up the subjects so they are thought of as coming from a single population, and the set of differences measured for each subject (for example, pre-test versus post-test) are thought of as one sample. The hypothesis test then boils down to a test for one population mean. For example, suppose a researcher wants to see whether teaching students to read using a computer game gives better results than teaching with a tried-and-true phonics method. She randomly selects 20 students and puts them into 10 pairs according to their reading readiness level, age, IQ, and so on. She randomly selects one student from each pair to learn to read via the computer game method (abbreviated CM), and the ot
Use to determine the sample size required to achieve a specific margin of error for confidence intervals or tolerance intervals. Conversely, you can estimate the margin of error based on sample size. Sample size for estimation Calculate the sample size required to http://support.minitab.com/en-us/minitab/17/topic-library/basic-statistics-and-graphs/power-and-sample-size/power-and-sample-size-analyses-in-minitab/ estimate a parameter within a specified margin of error. In Minitab, choose Stat > Power and Sample Size > Sample Size for Estimation Sample size for tolerance intervals Calculate the sample size required to control the coverage of a tolerance interval using a specified margin of error. In Minitab, choose Stat > Power and Sample Size > Sample Size for Tolerance Intervals Hypothesis tests Use hypothesis margin of tests to determine whether a population parameter differs from either a specified value or a different population parameter. 1-sample Z Examine the relationship between power, sample size, and difference for a 1-sample Z-test. In Minitab, choose Stat > Power and Sample Size > 1-Sample Z. Use a 1-sample z-test when you know the standard deviation of the population. 1-sample t Examine the relationship between power, sample margin of error size, and difference for a 1-sample t-test. In Minitab, choose Stat > Power and Sample Size > 1-Sample t. 2-sample t Examine the relationship between power, sample size, and difference for a 2-sample t-test. In Minitab, choose Stat > Power and Sample Size > 2-Sample t. Paired t Examine the relationship between power, sample size, and difference for a paired t-test. In Minitab, choose Stat > Power and Sample Size > Paired t. 1 proportion Examine the relationship between power, sample size, and comparison proportion for a 1 proportion test. In Minitab, choose Stat > Power and Sample Size > 1 Proportion. 2 proportions Examine the relationship between power, sample size, and comparison proportion for a 2 proportions test. In Minitab, choose Stat > Power and Sample Size > 2 Proportions. 1-sample Poisson rate Examine the relationship between power, sample size, and comparison rate for a 1-sample Poisson rate test. In Minitab, choose Stat > Power and Sample Size > 1-Sample Poisson Rate. 2-sample Poisson rate Examine the relationship between power, sample size, and comparison rate for a 2-sample Poisson rate test. In Minitab, choose Stat > Power and Sample Size > 2-Sample Poisson Rate. 1 varia
