APA Write-Up for Between-Groups ANOVA (Two Groups)

Description

Generates an APA-style paragraph reporting a between-groups ANOVA result, with hypothesis-driven conclusions that compare expected vs. actual results.

Usage

apa_bg_anova_writeup(
  anova_results_list,
  iv_name,
  dv_name,
  group_labels = NULL,
  hypothesis = NULL,
  alpha = 0.05,
  include_effect_size = FALSE,
  effect_size_type = "partial_eta_sq"
)

Arguments

anova_results_list Output from bg_anova_answers().

iv_name Character. Descriptive name for the IV (e.g., "condition").

dv_name Character. Descriptive name for the DV (e.g., "recall accuracy").

group_labels Character vector of length 2. Labels for IV levels (e.g., c("control", "experimental")).

hypothesis

List with hypothesis details:

direction: Expected direction: "group1_higher", "group2_higher", or NULL
rh_text: Optional. Full RH statement for custom phrasing.

If NULL, generates a generic non-directional APA writeup.

alpha Significance level. Default 0.05.

include_effect_size Logical. Include effect size in output. Default FALSE.

effect_size_type Character. Type: "partial_eta_sq", "eta_sq", or "omega_sq". Default "partial_eta_sq".

Value

A character string with the APA write-up.

Examples

library("psych350lab")

result <- bg_anova_answers(data, "condition", "score")

writeup <- apa_bg_anova_writeup(
  result,
  iv_name = "training condition",
  dv_name = "test performance",
  group_labels = c("control", "trained"),
  hypothesis = list(
    direction = "group2_higher",
    rh_text = "trained participants would perform better than control participants"
  )
)
cat(writeup)
