About Effect Size & C.I. Reporter

The Effect Size & C.I. Reporter is a Shiny application designed to help users analyze and visualize the effect sizes of different variables in a dataset. The app focuses on calculating Cohen's d or Mean Difference, measures of effect size, along with confidence intervals (95%, 85%, and 75%) and standard errors.

Please note that the app is still under development. Your constructive feedback is valuable to me.

Functionality

The app allows users to:

• Upload a CSV file containing their data.

• Select a factor column to analyze.

• Choose specific levels of the factor to include or exclude.

• Define a control group for comparison.

• Select multiple test variables to analyze.

• Customize the appearance of the plot, including titles, colors, sizes, and text.

• Calculate Cohen's d or Mean Difference and visualize the effect sizes with confidence intervals.

• Optionally display p-values and effect sizes on the plot.

• Download the plot as PNG or SVG.

How it Works

The app processes the uploaded CSV file and allows users to select a factor column and its levels for analysis. Users can define a control group and select test variables to compare against this control. The app calculates Cohen's d or Mean Difference for each variable, comparing the selected levels to the control group, and visualizes the results in a customizable plot.

Confidence intervals (95%, 85%, and 75%) and standard errors are calculated and displayed on the plot. Users can also choose to display p-values and effect sizes on the plot. The plot can be downloaded in PNG or SVG format for further use.
