Step-by-step explanation:
As we know, Scatter plots resembles line graphs in that they are plotted on the x and y axis and the purpose of a scatter plot is to shows if the variables are related to each other. If yes, they can draw a line of best fit which can expose or go through most of the points in the plot.
Given the information in the question, we know:
"they collected information of texting speed according to age"
=> We have 2 variables here which are age and (texting speed)
Step 1:
- Label the x-axis the input variable (age)
- Label the y-axis the output variable (texting speed)
Step 2: Plot the points according to age and texting speed
Hence, from that plot, it could have two cases in the relation of age and texting speed which are "the more time, more text is written", or "the less time, more text is written".
