The population mean symbol
Webb23 juli 2024 · In statistics, Greek symbols usually represent population parameters, such as μ (mu) for the mean and σ (sigma) for the standard deviation. A statistic is a characteristic of a sample. If you collect a sample and calculate the mean and standard deviation, these are sample statistics. WebbNote: In this manual, the B symbol next to a sample operation indicates degrees, while the * symbol indicates radians. Fix Sci Norm Specifies the number of digits for display of a calculation result. Fix: The value you specify (from 0 to 9) controls the number of decimal places for displayed calculation results. Calculation results are rounded off
