Statistical tests like t-tests or ANOVA can be used to determine if two samples are significantly different. These tests compare means of the samples, account for sample size, and calculate a p-value to determine if the difference is significant. A p-value below a chosen significance level (commonly 0.05) indicates that the samples are significantly different.
because
two samples are independent if they are drawn from two different populations, and/ or the samples have no effect on each other. eg: We want to estimate the difference between the mean salaries of all male and all female executives. We draw one sample from the population of male executives and another from the population of female executives. These two samples are independent because they come from different populations and the samples have no effect on each other
It is recommended to take multiple radon air samples in different locations within the basement to ensure an accurate representation of radon levels. At least two samples are typically suggested for a basement of that size. It is ideal to place the samples in areas where people spend most of their time to get a better idea of radon exposure in those living or working spaces.
These viruses are not living but there are two labs where samples are kept. One is at the CDC in the USA and one in Russia.
I don't know what experiment you're conducting, but when the directions tell you explicitly that you need to use a fresh utensil, then there must be the potential for contamination. Most likely using a different toothpick prevents the contents of slide one from crossing to slide two, which could invalidate your results.

Gypsum is soluble in water - Talc isn't

Two samples of blood may be taken from the same person to compare test results over time (e.g., to monitor disease progression or treatment effectiveness), to confirm test results, or to perform different types of tests that require separate samples. Having multiple samples can provide more reliable and accurate information about a person's health status.
If you apply two different antibiotics to two bacteria samples and they grew at the same pace, those antibiotics are equally effective or ineffective. Depending on the rate of growth, they may be unsuitable for use in treating an infection with that bacterium.
If all the same samples and factors are used.
If two samples of elements each represent one mole, then they will contain the same number of atoms. This is because one mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. Therefore, both samples will have the same number of atoms, even if they are different elements.
the hotter sample because energy flows from hot to cold until the two are the same temperature.
A heterogeneous mixture has two or more distinct phases with different characteristics. Because of this, two random samples of a heterogeneous mixture may have different compositions. For example, the phases in mud are the water and soil particles, which remain distinct from one another. These phases are not necessarily visible, but may exist as microscopic clusters or particles. By contrast in a homogeneous mixture any two random samples will be identical.

The streak of a mineral can distinguish between two samples that have the same color. The streak is often a different color. To test streak, use a streak plate. This is a piece of unglazed porcelain, like the back side of a tile.
