The graph shows the data of texting speed according to time.

A graph has time (minutes) on the x-axis and texting speed (words per minute) on the y-axis. Points are at (1, 14), (1, 18), (2, 10), (2, 15), (2, 17), (3, 14), (4, 10), (4, 15), (5, 6), and (5, 10).

Use the scatterplot to determine if there is a relationship. If there is a relationship, explain it.
Yes, there is a relationship. As time increases, texting speed increases.
Yes, there is a relationship. As time increases, texting speed decreases.
Yes, there is a relationship. As texting speed increases, time increases.
No, there is no relationship displayed.

To analyze the scatterplot data you provided, let's observe the points plotted:

  • (1, 14), (1, 18) - At 1 minute, there are two values for texting speed (14 and 18 words per minute).
  • (2, 10), (2, 15), (2, 17) - At 2 minutes, there are three values (10, 15, and 17 words per minute).
  • (3, 14) - At 3 minutes, the speed is 14 words per minute.
  • (4, 10), (4, 15) - At 4 minutes, there are two values (10 and 15 words per minute).
  • (5, 6), (5, 10) - At 5 minutes, there are two values (6 and 10 words per minute).

From the information given, the relationship between time (in minutes) and texting speed (in words per minute) is not positively or negatively consistent.

When examining the data:

  • The texting speed fluctuates at some time intervals rather than showing a clear trend (it does not consistently increase or decrease with time).
  • For example, at 2 minutes, texting speed has values from 10 to 17, and then speeds varies at 5 minutes between 6 and 10.

Given this analysis, the most accurate choice is:

No, there is no relationship displayed.

The variations in texting speed suggest that, while there may be instances of increasing or decreasing speed, there isn’t a clear overall relationship as time progresses.
