Measuring and Analyzing Snake Lengths

Joaquin, a zookeeper, measures the largest snakes in the reptile room monthly to track their growth. He uses a tape measure but sometimes resorts to a ruler, making repeated measurements due to its smaller size. Joaquin records the lengths of 10 snakes to the nearest foot and displays this data in a line plot. This visualization helps him see the distribution of snake sizes, noting that many are 4 and 12 feet long, and most are over 6 feet. The line plot allows Joaquin to identify trends in snake growth and size distribution.

What tool does Joaquin primarily use to measure the snakes?

• A tape measure

• A caliper

• A yardstick

• A ruler

Why does Joaquin use a ruler instead of a tape measure sometimes?

• The ruler is more precise

• He misplaces the tape measure

• The ruler is easier to handle

• He prefers the ruler for accuracy

How does Joaquin record the snake measurements?

• To the nearest centimeter

• To the nearest foot

• To the nearest inch

• To the nearest meter

How many snakes did Joaquin measure?

• 20

• 5

• 10

• 15

What is the purpose of creating a line plot with the snake measurements?

• To visualize the data and identify trends

• To calculate the average snake length

• To determine the oldest snake

• To compare with other zoos

What trend does Joaquin notice from the line plot?

• No snakes are over 12 feet long

• Most snakes are over 6 feet long

• Most snakes are under 4 feet long

• All snakes are exactly 6 feet long

What does Joaquin use to represent each snake on the line plot?

• A square

• An X

• A triangle

• A circle
