Graphs and Data — Answer Key
Part A: Sort the Words
Sort each word or number into the correct category box.
1. A class voted on favorite pets. Sort each pet by its number of votes.
More Than 5 Votes
cats: 8 votesfish: 6 voteshamsters: 9 votes 5 or Fewer Votes
dogs: 3 votesbirds: 2 votesturtles: 4 votes Pets with more than 5 votes are cats (8), fish (6), and hamsters (9), since each of those numbers is greater than 5. Dogs (3), birds (2), and turtles (4) all have 5 or fewer votes, so they go in the smaller group.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The most popular pet is hamsters.
Hamsters got 9 votes, which is more than any other pet on the chart. The pet with the highest number is the most popular.
2. The least popular pet is birds.
Birds received only 2 votes, the lowest count of any pet. The smallest number on the chart shows the least popular choice.
3. A tally chart uses tally marks to record data.
Tally marks are short straight lines used to count items one at a time, with every fifth mark drawn diagonally across the first four. That is why a chart that records data this way is called a tally chart.
4. How many more students chose cats than dogs? 5.
Cats got 8 votes and dogs got 3 votes, and 8 - 3 = 5. Subtraction tells us how many more one group has than another.
5. In a pictograph, a picture represents a certain number of items.
On a pictograph, each small drawing stands for a set number of items, like one apple meaning 2 students. The picture is the symbol that does the counting.
Part C: True or False?
Read each statement. Circle True or False.
1. Hamsters got the most votes.
True False
True. Hamsters had 9 votes, which is the largest number in the data, so they got the most votes.
2. A bar graph with a taller bar means fewer items.
True False
False. On a bar graph, a taller bar means a larger number of items, not fewer. Bar height grows with the count.
3. Dogs and turtles together got 7 votes.
True False
True. Dogs got 3 votes and turtles got 4 votes, and 3 + 4 = 7, so together they total 7.
4. Fish got more votes than cats.
True False
False. Fish got 6 votes and cats got 8 votes, so cats got more, not fish.
