Mobile phone use and brain tumour data

Description

A dataset from Field, A. P. (2023). Discovering statistics using R and RStudio (2nd ed.). London: Sage.

Usage

tumour

Format

A tibble with 102 rows and 3 variables

Details

Mobile phones emit microwaves, and so holding one next to your brain for large parts of the day is a bit like sticking your brain in a microwave oven and pushing the 'cook until well done' button. If we wanted to test this experimentally, we could get six groups of people and strap a mobile phone on their heads, then by remote control turn the phones on for a certain amount of time each day. After six months, we measure the size of any tumour (in mm^3) close to the site of the phone antenna (just behind the ear). The six groups experienced 0, 1, 2, 3, 4 or 5 hours per day of phone microwaves for six months. The fictitious data contains three variables:

• id: participant ID

• usage: how many hours per day were the phones active for (0, 1, 2, 3, 4, or 5 hours)

• tumour: Size of any tumour (in mm^3)
