Statistics:

• p - population proportion (categorical)

• p̂ - sample proportion (categorical)

• μ - population mean (quantitative)

• x̄ - sample mean (quantitative)

• σ - population standard deviation (SD)

  • σ² - variance

• sₓ - sample standard deviation

• ∩ - intersection of two events (the occurrence of both events at the same time)

• ∪ - union of two events (the occurrence of either event or both events)

• z - aka z-score is how many standard deviations a point is from the mean

• ∝ - Significance level

• χ - chi (pronounced “kye”) for chi-square test statistics

Calculus:

• ∞ - Infinity

  • In Superscript: ₓ → ∞ | ₙ → ∞

• ∫ - Integral

  • ₐ∫ᵇ

• Σ - Sigma

  • Simple premade format: ᵢ₌₁Σⁿ

  • OR: [ ₋(i=1)Σ^6 ] where the ₋ is subscript and ^ is superscript

• ᵢ - subscript i | f(cᵢ)

• ∆ - Delta | ∆x

General Math:

• • - Multiplication

• √ - root symbol

• π - pi

• ≤ - Less than or equal to

• ≥ - Greater than or equal to

• ≠ - not equal to

• ⋃ - Union

• ± - Plus/Minus Combined

• → - Arrow
