Bern (p) Name: Bernoulli distribution. 2. 3. statistics, etc. Statisticians acquire, organize, and analyze data. Statistics is the study of numerical information, called data. Median = (7 + 1) / 2 2. Population standard deviation = σ = sqrt [ Σ ( Xi - μ )2 / N ] 3. Median = 8 / 2 3. parameters, N nonmissing is the number of cells that contain actual data. N missing is the number of cells that contain the missing value symbol *. μ = ( Σ X i) / N. The symbol ‘μ’ represents the population mean. The total number of observations is the sum of N and the number of missing values. (i.e., parameters); and lower-case letters refer to sample attributes It takes lots of data to determine the population SD with precision. Standardized score = Z = (X - μ) / σ 6.
