Students need to master these symbols because these symbols are the standard nomenclature in statistical reasoning. In general, Greek letters are used for measures of the population (called “parameters”) and Latin letters are used for measures of one or more samples (called “statistics”).
Complex numbers. {r(cos θ + i sin θ)}n = rn(cos nθ + i sin nθ) eiθ = cos θ + i sin θ. 2 π k i. The roots of zn = 1 are given by z = e n , for k = 0, 1, 2, ..., n – 1.
p. Discrete probability distribution for the probability of number of successes in n independent random trials under the identical conditions. If X follows B (n, p) then, P (X = r) =. n C pr ( 1 p. n r. r ) , Where, 0 < p <1, r = 0,1,2, ...n. Binomial Distribution.
Sampling Distributions and Inferential Statistics. Standardized test statistic: statistic − parameter standard error of the statistic. Confidence interval: statistic ± ( critical value )( standard error of statistic ) Chi-square statistic: 2 ∑ ( observed − expected ) 2. χ = expected III.
Mathematical Formulae and Statistical Tables Issue 1 uly 2017 Pearson Education Limited 2017 Introduction The formulae in this booklet have been arranged by qualification. Students sitting AS or A Level Further Mathematics papers may be required to use the formulae that were introduced in AS or A Level Mathematics papers.
The formula for the normal distribution is: f(x) = 1 √2πσ2e − (x − μ)2 2σ2, However, what are e and π doing there? π is about circles and the ratio to its diameter, for example. e is mostly about exponential functions, specifically about the fact that d dxex = ex.
