Introduction
The FINA Junior World Diving Championships is a elite dive meet where top divers around the world under the age of 18 compete. Each diver completed 9 dives, all of which contributed to their overall score. Each dive is scored by 7 judges. Each judge gives a score individually on a scale of 1-10 at half-point increments based on execution of the dive. 10 represents perfect execution, while 0 represents failed execution. The two lowest and the two highest scores of the judges are voided, and the other three are added together. The sum of the three judges is then multiplied by the difficulty of the attempted dive. The product represent the points earned for that dive. The overall score is calculated by adding together the points earned on each dives.
In this worksheet, we will determine if there are statistical differences in mean total points scored between 16, 17, and 18-year old divers. Understanding how total score differs between different aged divers may tell us something about the importance of age, experince, and skill level in scoring points in diving.
Data
The data set contains 360 rows and 15 columns. Each row represents a completed dive from a diver in the preliminary results of women (aged 16-18) 1m springboard from the 2022 FINA World Junior Championships. Each diver completed 9 dives, so there is 9 rows per diver.
