Soccer Heights

Heights for a sample of 100 soccer players by position

Motivation

A researcher wants to investigate whether there are differences among the mean height for different positions (Goalkeeper, Defender, Midfield, Attack, or Missing) of soccer players. Goalkeepers are typically thought to be taller than other positions to make up in wingspan to cover the goal better. The dataset contains information on each player including their name, position, preferred foot, and height. For this analysis, only the position and height of the player will be used. A sample of 20 players was taken from each position for this analysis.
