Sampling Plans zSimple Random Sample zEach sampling unit has an equal probability of being sampled with each selection. zCan perform simple random sampling if: zEnumerate every unit of the population zRandomly select n of the numbers and the sample consists of the units with those IDs zOne way to do this is to use a random number table or random number generator

They reported that seven other studies with larger samples found a statistically significant difference in heart rate with a music interven-tion. Because of this and the other findings they identified, they be-lieve their study was underpow-ered, meaning its sample size was

with the bias statistically, as for example by age-adjustment of rates. To rule out reason 3, we test for statistical significance. If the test shows that the observed difference is too large to be explained by random variation (chance) alone, we state that the difference is statistically significant and thus conclude that drug A is superior to ...

Bootstrapping to create larger data sets by taking random samples from initially small samples. The key assumption in this process is that the sample data is representative of the entire data set. With the newly created data set, we were able to estimate an interval for mean shortfall amount given a desired confidence level.

Statistical versus Practical Significance - The Atrium
When reading statistically significant study results, keep the following warning signs in mind: -Observe the sample size used to obtain study results. Remember that if the study is based on a very large sample size, relationships found to be statistically significant may not have much practical significance.
