statistical significance
The samples must be randomly selected, independent, and normally distributed. The following are necessary to use a t-test for small independent samples. 1. The samples must be randomly selected. 2. The samples must be independent. 3. Each population must have a normal distribution.
A composite sample is taken over a period of time, while a grab sample is a snap shot of what is in your well at the time you take the sample. Homeowner samples are generally grab samples.

sampling time is the number of samples per second taken from a continuous signal to make it discrete and holding time is the time between two samples..
different samples of respondents from the population complete the survey over a time period
It calculates the difference between each set of pairs, and analyzes that list of differences. The P value answersthis question: If the median difference in the ... If your samples are small and there are no tied ranks, Prism calculates an ... The whole point of using a paired test is to control for experimental.
I don't know what you observed, but I observed everything - elements and compounds and even some atoms!

Because they are based on samples and outcomes vary between different samples.
Restriction enzymes cleave, or open, the DNA so that a sample can be taken and gel electrophoresis can separate the strands of DNA. From there, DNA probes bind to certain strands in each sample and DNA fingerprints can show the differences.
You are testing the difference between two means of independent sample and the population variance are not known. from those population you take two samples of two different size n1and n2. what degrees of freedom is appropriate to consider in this case
Western blot can be semi-quantitative. This means that you cannot determine absolute protein levels, but you can detect differences between groups. For example, if you have 4 different samples, a western blot will be able to tell you which samples have the most of any specific cellular protein. Quantitation is usually perfomed using "densitometry software" such as NIH ImageJ.

one sample: 1, 2, 3, 3, 4, 5 another sample: -5, -2, 3, 3, 8, 11 These two samples have the same mean, median and mode. It's easy to make some of the elements of the samples different and keep the mean and median the same. However, since the mode is a most frequently observed value it has to be common to both samples. So to achieve a common mode some of the observed values must be the same.
