An example of data from a study with a two dependent groups design used in Chapter 8 of the book Introduction to the New Statistics.

1	emotion_heartrate

A data frame with 68 rows and 5 variables:

id: Respondent identifier
first_emotion: anger or happiness, determined by coin flip
hr_baseline: Heart rate measured in beats per minute during baseline period prior to emotion recall
hr_anger: Heart rate measured in beats per minute during recall of times of intense anger
sr_anger: Self-reported intensity of feeling angry during angry recall, scale from 0 - 8

To what extent do emotional responses alter heart rate? To find out, participants were asked to recall memories of intense happiness or anger. Heart rate was measured using a cell phone app in beats per minute. Heart rate was measured for each participant before emotion recall (hr_baseline), during anger recall (hr_anger), and during happiness recall (hr_happiness). The order of emotion recall was counterbalanced.

As a manipulation check, participants also rated how intensely they were able to feel each emotion during the recall task on a scale from 0 (absolutely not intense) to 8 (extremely intense) .

This is a simplified dataset that has data only for baseline and anger. The data for happiness is not included here. Also, participants who had missing heart rate data due to data collection errors have been deleted.
