1-2. Different ways of presenting data can tell you different things. For example, some of your questions might have been easy to answer with an organized table of data However, other questions can be easier to answer if the data is arranged in a different way, such as in a histogram like the one shown below Look carefully at the graph. Use it to try to answer the questions below. If you cannot answer a question, explain why not. Between which two numbers on the graph did the most frogs jump? a. 4 3 2 Typical frogs jump between what two jump lengths? b. 180 190 200 210 220 230 240 250 260 Jump Length (inches) c. Were there any unusually long or short jumps? d. How many frogs are represented on this histogram? e. Half the frogs jumped less than how many inches? Unit 1: Describing One-Variable Data
Explanation / Answer
(a)
Between 220 and 230 inches, most frogs jumped because it has the highest highest.
(b)
Between 220 and 230, because this is where the graph has highest height.
(c)
Yes, There was one jump between 180-190 and another between 250-260.
(d)
Number of frogs represented = 1+2+8+4+1 = 16 frog jumps
(e)
This can not be determined, because half the number means 8, and this figure can not be determined from the given graph.
Hope this helps !
