However, during the 1.0 msec between samples, the encoder moved 3 counts, or 0.009 rad, or at an apparent rate of 9 rad/sec (for convenience, the resolution in this example is 0.003 rad and the sample time is 0

Both samples aresimple random samples. The samples areindependent. Each sample includes at least 10 successes and 10 failures. The Variability of the Difference Between Proportions To construct aconfidence intervalfor the difference between two sample proportions, we need to know how to compute thesta...
A stratified random sample is a statistical procedure that takes multiple random samplings from different subsets, or "strata", of the population. This is more complicated than a simple random sample but ensures that the final sample will be a representative cross-section of the popu...
t is the test statistic (look-up using the t-distribution based on the sample size for two-sided area). See Technical Note 1. Example 1: Comparing two System Usability Scale (SUS) means For example, in a test between two expense-reporting applications, 26 users worked (in random order)...
The sampling method for each population issimple random sampling. The samples areindependent. Each sample point can result in just two possible outcomes. (We call one of these outcomes a success and the other, a failure. The proportion of successes in the sample is denoted by p.) ...
