Question

the graph shows the number of internet downloads of a song compared to the number of times it is played on the radio. what can you conclude from the data? check all that apply.
the number of times a song is played on the radio affects its number of downloads.
increased radio play affects the download demand for all songs equally.
even though there was very high radio play, the downloads of one song remained very low.
in general, increased radio play does not affect the number of downloads.

Explanation:

• The scatter - plot shows a relationship between radio play and downloads. Since there is a pattern (even if not a perfect one), the number of times a song is played on the radio affects its number of downloads.
• There is one point with very high radio play but low downloads, so “Even though there was very high radio play, the downloads of one song remained very low” is correct.
• The scatter - plot does not show that increased radio play affects all songs equally (as there is variation in the data points). Also, the general trend (ignoring the out - lier) shows that radio play and downloads are related, so “In general, increased radio play does not affect the number of downloads” is incorrect.

Answer:

• The number of times a song is played on the radio affects its number of downloads.
• Even though there was very high radio play, the downloads of one song remained very low.
