The formula for calculating the mean of a sample, represented by the symbol "" in statistics, is to add up all the values in the sample and then divide by the total number of values in the sample. This can be written as: x / n, where x represents the sum of all values in the sample and n is the total number of values in the sample.
The formula for calculating uncertainty in a dataset using the standard deviation is to divide the standard deviation by the square root of the sample size.
The average velocity of the particles in the sample. By measuring the motion of each particle and calculating the average, you can determine the typical speed and direction of motion for the particles in the sample.
You would be measuring the sample's temperature. Temperature is related to the average kinetic energy of the particles in a sample. By measuring the motion of all particles and calculating the average, you are essentially determining the average kinetic energy and thus the temperature of the sample.
Three half lives have elapsed. This can be determined by calculating how many times the original sample size must be halved to get to one eighth: (1/2) * (1/2) * (1/2) = 1/8.
Some sample problems in free falling bodies include determining the time it takes for an object to fall a certain distance, calculating its final velocity upon impact with the ground, and finding the height from which an object was dropped based on its impact velocity. These problems typically involve using equations of motion like the kinematic equations to solve for various unknown quantities.

The formula for calculating uncertainty in a dataset using the standard deviation is to divide the standard deviation by the square root of the sample size.
A representative sample is one where the statistics of the sample are the same as the statistics for the parent population.
a pure substance! ;)
The same basic formula is used to calculate the sample or population mean. The sample mean is x bar and the population mean is mu. Add all the values in the sample or population and divide by the number of data values.
Information obtained from the sample can be extrapolated to the whole population using statistics.

The bulk density of magnetite can be calculated using the formula: Bulk Density = (mass of material) / (volume of material). This formula involves measuring the mass of the magnetite sample and calculating its volume to determine the bulk density.
Statistics: Survey of an entire population, as opposed to a sample survey.
n is the sample size.
The sample mean may differ from the population mean, especially for small samples.
