The dot plots below show the scores for a group of students for two rounds of a quiz: two dot plots are shown one below the other. the title for the dot plot on the top is round 1 and the title for the bottom plot is round 2. below the line for each dot plot is written score. there are markings from 1 to 5 on the line at intervals of one. there are 2 dots above the mark 2, there are 3 dots above the mark 3, there are 2 dots above the mark 4 and there is 1 dot above the mark 5. for the bottom dot plot there are there are 4 dots above the mark 4 and there are 4 dots above the mark 5. which of the following inferences can be made using the dot plots? there is no overlap between the data. round 2 scores are lower than round 1 scores. round 1 scores are higher than round 2 scores. the range of round 1 is greater than the round 2 range.

The inference that can be made using the dot plot is:

    The range of round 1 is greater than the round 2 range.

Step-by-step explanation:

Round 1:

Score                Frequency

  1                          0

  2                          2

  3                          3

  4                          2  

  5                          1

Hence, the minimum score of Round 1 is: 2

maximum score is: 5

Hence, Range=Maximum value-Minimum score

                      =5-2

                       =3

Similarly, Round-2

Score                Frequency

  1                          0

  2                         0

  3                          0

  4                          4  

  5                          4

Hence, the minimum score of Round 1 is: 4

maximum score is: 5

Hence, Range=Maximum value-Minimum score

                      =5-4

                       =1

The scores of round 2 are higher than round-1.

Since round 2 have a higher frequency for higher scores as compared to round-1.

Hence, Range of round 1 is greater than the range of Round-2.
