Descriptive Statistics: LaTeX Formatting Guide explains center, spread, quantiles, outliers, samples, and reporting conventions.
Core notation for Descriptive Statistics
In descriptive statistics, the notation usually represents observations, samples, estimators, parameters, and uncertainty summaries. The table below gives a compact starting set for descriptive statistics; define any local variation before the first calculation.
| Concept | Notation | How to read it |
|---|---|---|
| Correlation | r=\frac{\operatorname{cov}(X,Y)}{s_Xs_Y} | standardized linear association |
| Observation | x_i | the i-th measured or observed value |
| Sample mean | \bar{x}=\frac{1}{n}\sum_{i=1}^{n}x_i | the arithmetic mean of n observations |
| Sample variance | s^2=\frac{1}{n-1}\sum_{i=1}^{n}(x_i-\bar{x})^2 | an unbiased variance estimate under the usual assumptions |
LaTeX patterns that preserve the structure
For descriptive statistics: guide, group arguments explicitly, use named operators, scale delimiters to the enclosed expression, and align rows at the mathematical relation being compared.
r=\frac{\operatorname{cov}(X,Y)}{s_Xs_Y}
x_i
\bar{x}=\frac{1}{n}\sum_{i=1}^{n}x_iFor descriptive statistics, keep multi-character labels inside \text{...} or an appropriate operator command. In descriptive statistics, use braces whenever a subscript, superscript, numerator, denominator, or radical contains more than one token.
Conventions to state beside the formula
- Distinguish population parameters from sample estimates.
- State whether variance uses n or n-1 in the denominator.
- Define the confidence level, tail convention, and rounding rule.
Renderer and export checks
Render one demanding descriptive statistics example in the actual destination. For descriptive statistics, compare the source, browser output, office-equation output, and exported PDF so grouping, indices, minus signs, and line breaks remain unchanged.
Accessibility and portability
Keep the descriptive statistics source selectable and editable. For an isolated character in descriptive statistics, Unicode text may be sufficient; for structured expressions, preserve LaTeX, MathML, or a native equation object. When an image of descriptive statistics is unavoidable, describe the operation, inputs, conditions, and conclusion rather than listing glyph names.
Verification checklist
- Recalculate one small sample by hand.
- Confirm the denominator and degrees of freedom.
- Report units for location and squared units for variance.
- Confirm every symbol used in descriptive statistics has one defined meaning in the local context.
- Reopen the exported file for Descriptive Statistics: LaTeX Formatting Guide and compare it with the editable source.
