Question

At the Olympic games, many events have several rounds of competition. One of these events is the men's 100100100-meter backstroke.

The upper dot plot shows the times (in seconds) of the top 888 finishers in the final round of the 201220122012 Olympics. The lower dot plot shows the times of the same 888 swimmers, but in the semifinal round.


Which pieces of information can be gathered from these dot plots? (Remember that lower swim times are faster.)

Answer 1

The dot plots show the times of the top 888 finishers in the final and semifinal rounds of the men's 100-meter backstroke event at the Olympic games. From the dot plots, we can gather information about the range, median, and distribution of swim times between the two rounds.

Step-by-step explanation:

The dot plots show the times of the top 888 finishers in the final and semifinal rounds of the men's 100-meter backstroke event at the Olympic games.

From the dot plots, we can gather the following pieces of information:

1. The range of swim times in the final round is larger than in the semifinal round, indicating that there is more variation in the final round.
2. The median swim time in the final round is faster than in the semifinal round, suggesting that the fastest swimmers made it to the final round.
3. There are more swimmers with slower times in the semifinal round compared to the final round, indicating that some swimmers did not advance to the final round.
