Descriptive statistics x = 1 n ∑ ∑ xi = xi n s x = 1 ∑ n x )2 − − 1 ( xi x ) 2 ∑ ( − = xi n − 1 y. Μ = x n weighted mean: Web understanding formulas for common statistics. X = ∑ ( w • x ) ∑ w x ∑ mean for frequency table: 2 pure mathematics algebra for the quadratic equation 0ax2 +bx +c =: Web statistics (0390) list of formulae and tables of the normal distribution. Web formulas and tables for ap statistics i. Web arithmetic series un = a + (n − 1)d sn = 1 n(a + l) = 1 n{2a + (n 2 − 1)d} 2 geometric series un = arn − 1 sn − n = a (1 r ) − r s∞ = a for r < 1 1− r summations ∑ r 2 = 1 n ( n + 1)(2 n + 1) 6 = 1 ∑ r 3 = 1 n 2 ( n 4 + 1) 2 = 1 binomial. After data has been collected, the first step in analyzing it is to crunch out some descriptive statistics to get a feeling for the data. A b b ac x 2 −±√(2 −4 ) = for an arithmetic series:
