Compute Dropout Statistics
Description
This is the second step in conducting dropout analysis with dropR
.
Outputs all necessary statistics to analyze and visualize dropout, such as
the sample size N of the data (and in each condition if selected), cumulative
dropout and remaining participants in absolute numbers and percent.
If no experimental condition is added, the stats are only calculated for the
whole data in total.
Usage
compute_stats(df, by_cond = "None", no_of_vars)
Arguments
df |
data.frame containing variable |
by_cond |
character name of condition variable in the data, defaults to 'None' to output total statistics. |
no_of_vars |
numeric number of variables that contain questions |
Value
A data frame with 6 columns (q_idx, condition, cs, N, remain, pct_remain) and as many rows as questions in original data (for overall data and if conditions selected again for each condition).
Examples
do_stats <- compute_stats(df = add_dropout_idx(dropRdemo, 3:54),
by_cond = "experimental_condition",
no_of_vars = 52)
