Question

These dot plots show the lengths (in feet) from a sample of crocodiles and
alligators. ​

Answer 1

Answer:

A. Alligators have a greater IQR because there were some very long alligators (high outliers).

Answer 2

The statement (A) centres: The crocodiles have a greater median length than the alligators and statement (B) Spreads: The lengths of the alligators are more spread out is correct.

What is dot plot?

A dot plot, also referred to as a dot chart or stripe graph, is a sort of simple histogram-like figure used in statistics for little data sets with values falling into a number of discrete bins.

For crocodile, from the dot plot:

Q1 = 16

Q3 = 18

IQR = 18 - 16 = 2

Mean of crocodile = 17.8

Variance = 52.92

For alligator, from the dot plot:

Q1 = 8

Q3 = 10

IQR = 10 - 8 = 2

Variance = 82.65

Thus, the statement (A) centres: The crocodiles have a greater median length than the alligators and statement (B) Spreads: The lengths of the alligators are more spread out is correct.
