## Shiny

Shiny web apps are online applications that use R on a server (instead of a local machine). These apps are based on the full power of the R language and environment for statistical computing, but do not require the user to install R or even know anything about R. The apps are generally very simple to use.

### Effect Sizes

- Standardized Mean Difference,
*d* - Standardized Mean Difference Using the Control Group Standard Deviation,
*d*.C - Transform
*r*into*d* - Transform
*d*into*r*

### Confidence Intervals

- Standardized Mean Difference, δ
- Standardized Mean Difference (Using Control Group Standard Deviation), δ
_{c} - Confidence Interval for a Population Contrast, Ψ
- Confidence Interval for a Population Standardized Contrast, ψ
- Signal-to-Noise Ratio,
*f*^{2} - Square Root of the Signal-to-Noise Ratio,
*f* - Proportion of Variance Accounted For in the Population (In the DV by Knowing the Levels of the Factor), ω
^{2} - Noncentral
*t*-Distributions - Noncentral
*F*-Distributions - Population Correlation Coefficient, ρ
- Population Coefficient of Determination (from a Regression Model), ρ
^{2}
