2 cards from this section. Quick, good the night before a test.
What is the deviation of a measurement of 8 from a mean of 10?
Remember to subtract the mean from the measurement.
What is the mean of the following numbers: 2, 4, 6, 8?
Add the numbers and divide by how many there are.
What does deviation measure?
Think about what deviation signifies in statistical data.
Is standard deviation a measure of accuracy or precision?
Reflect on the difference between consistency and correctness.
Given the following set of measurements: 10, 12, 14, 16, and 18. Calculate the mean and standard deviation, then interpret what the results indicate about the data's reliability.
Don't forget the step of calculating squared deviations when finding standard deviation.
Experiment X has a mean of 100 and a standard deviation of 20. Experiment Y has a mean of 100 and a standard deviation of 10. Which experiment demonstrates greater precision, and why?
Consider the spread of each set of measurements around their mean.
