Going back to the earlier data set of human second molar breadth, calculate the following:What is the range (measured to 0.1 mmm)______ What is the standard deviation (measured to 0.1 mmm)______ What is the coefficient of variation (measured to 0.1)______
举一反三
- What can be measured with a multimeter?
- 中国大学MOOC: A BJT has measured dc current values of IB = 0.1 mA and IC = 8.0 mA. When IB is varied by 100 μA, IC changes by 10 mA. What is the value of the βdc for this device?
- When measuring the dispersion of the sample mean, the statistics to be used are ( ) . A: Coefficient of variation B: The standard deviation C: Standard deviation of the mean D: Range value
- Given the following information: Standard deviation = 8 Coefficient of variation = 64% The mean would then be
- Standard parts can be measured（）
