What is the formula for calculating the mean of a sample, represented by the symbol "" in statistics?
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.

What is the formula for calculating uncertainty in a dataset using the standard deviation?
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.
If you were able to measure the motion of all particles of a sample and you use data to find the average you would actually be measuring?
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.
If you were able to measure the motion of all of the particles of a sample and you used this data to find he average you would actually be measuring?
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.
Is a radioactive sample has decayed until only one eighth of the original sample remains unchanged how many half lives have elapsed?
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.
What are the sample problems in free falling bodies?
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.

What is the formula for calculating uncertainty in a dataset using the standard deviation?
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.
What is represenatative sample of population?
A representative sample is one where the statistics of the sample are the same as the statistics for the parent population.
What is a sample of matter either a single element or a single compound?
a pure substance! ;)
Difference between calculating the sample mean and the population mean?
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.
What is the relationship between a sample and population is statistics?
Information obtained from the sample can be extrapolated to the whole population using statistics.

What is bulk density formula for magnatite?
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.
What is census in statistics?
Statistics: Survey of an entire population, as opposed to a sample survey.
What is n in statistics?
n is the sample size.
Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.
