Summary of the different descriptive statistics The analysis first examines the differences between the two sexes. Although the ratio between the Summer Olympics and the Winter Olympics is indeed different, men happen to be dominant. My first assumption is that the ratio of women to men has increased ove r time. I began to dive into it. There are significant differences between male and female participants not only in terms of expected height and weight, but also in terms of age. The first two differences can be attributed to biology. Although the latter may require more than just: it is worth considering social factors at the same time. Another interesting fact is that the age gap in the Winter Olympics is much smaller (~2.8 years old and 1.5 years old) Another analysis of the number and ratio of medals is needed. I checked the ratio of total medal winners and the changes in the ratio of different medals: In the last century, the medal ratio fluctuated greatly in the two competitions, but eventually stabilized. This can be interpreted as establishing norms on these issues. The relative percentages of gold, s ilver and bronze medals have also stabilized, which may be due to the reasons mentioned above. Submit 2 - 3 key points you may have discovered about the data, e.g. new relationships? Aha's! Did you come up with additional ideas for other things to review? I noticed that compared wit h the Summer Olympics, the age gap between male and female participants in the Winter Olympics is smaller. I found that in the recent Olympics, the percentage of participants who won medals and the ratio of medals (gold:silver:bronze) have stabilized. I re alized that there are important differences in the number of participants in the two Olympics (summer and winter), so it must be analyzed separately. Did you prove or disprove any of your initial hypotheses? If so, which one and what do you plan to do next ? My first assumption is that the ratio of women to men has increased over time. I will create a year - by - year Female to Male ratio table, and then draw a line graph to see the relationship. This assumption seems to be correct. Over time, the ratio of men t o women has indeed decreased. However, there is an interesting detail: during the Second World War, the proportion of the Summer Olympics dropped sharply, but then it resumed its growth momentum. Without further analysis, I cannot explain this phenomenon. Additional questions I am seeking to answer I will test my next two hypotheses with the help of A/B testing. These assumptions are: H2: In the Winter Olympics, the annual performance of different countries varies greatly. H3: A country’s performance in the Winter Olympics is related to its performance in the Summer Olympics.
