Olympic swimming has been a sport at every summer Olympics and contains a diverse background of athletes from over 150 countries. Examining the results of this event allows us to have a detailed look into the trend of the athletes that competed over the years.

The dataset contains 606 rows and 10 variables. Each row represents a swimmer that completed their race in the Olympics.

Variable Description
Location hosting city of the Olympics that the swimmer competed in
Year year that the swimmer competed
dist_m distance in meters of the race
Stroke Backstroke, Breaststroke, Butterfly, or Freestyle

Data file



  • Construct a hypothesis test to examine if swimmers have gotten quicker over the years
  • Analyze the trend and correlation of a scatterplot of years and times and explain it’s meaning in context
  • Examine side-by-side boxplots to see the relationship between different strokes and times between males and females
