Ms. Meyer asked her students about how many of pets they owned.
She created a tally chart to show the results.
She also made a bar graph to present her data.
Is there another way she can show the results of her survey?
Yes, she can use a line plot.
A line plot is a graph that uses X's to show the number of times a response appears in the set of data.
X's are placed above the responses.
This is the line plot for the survey that Ms. Meyer's did.
We can answer a lot of questions just by looking at it.
How many students have 2 pets?
We just count the X's above the number 2.
There are 7 students that own two pets each.
How many students have fewer than 2 pets?
This question is asking you to add the X's over a range of numbers.
Tip: The word "fewer" means you include numbers that are less than a certain point.
In this case, it's the numbers that are less than 2.
We count the X's above 0 and 1.
How many did you get?
Yes, 12 students own fewer than two pets.
How many students have more than 2?
We count the X's above 3 and 4.
Tip: Don't include the X's above 2. It has to be the numbers more than 2.
We see that 3 students have more than 2 pets, because there are 3 X's.
How many students have 2 or more pets?
This question is asking you to add the X's over a range of numbers.
Tip: The word "or" means you include numbers starting from a certain point in the number line.
In this case, we start counting the X's above 2 to 4.
2 has 7 X's.
3 has 2 X's.
4 has 1 X.
Now we add all the X's.
7 + 2 + 1 = 10
So there are 10 students with two or more pets.
How many students have no pet at all?
We count the X's above zero.
3 students have zero pets.
How many students were surveyed?
To answer this, we count the X's above all the numbers.
There are 22.
Great job reading this line plot. 👏
Now let's create one together.
Ms. Meyer did another survey. She asked her students about their favorite type of pet.
Here's a table of the results.
Let's make a line plot for this.
1️⃣ The first step is to draw a line.
2️⃣ Draw one tick mark on the line for each category.
3️⃣ Write the name of each category, the type of pet, below each tick mark.
Tip: When writing the labels, make sure there's enough spacing between the labels.
4️⃣ Then, write a label under the line to show what the labels are all about. Here, we wrote "Pets".
5️⃣ Next, write X's above the numbers.
How many X's do you write for each number?
For this, we use the table above.
Six students said their favorite pet is a cat. Write 6 X's above "cat".
Dog is the favorite of eight students. There should be 8 X's above "dog".
Continue writing X's for "fish", "turtle", and "rabbit".
Make sure to double-check if you have the correct number of X's above each pet.
6️⃣ Finally, add a title at the top of your line plot.
Ms. Meyer's line plot is complete. ✅
Now, let's start reading it.
Which animal is the most loved pet?
You're right! It's the dog. It has the most X's above it.
Which is the least loved pet?
Yes, the turtle. 🐢
Which animals were chosen by the same number of people?
Very good. The fish and the rabbit. 🐠🐰 They both have three X's.
Great job. 👏
You just learned how to create line plots and read them, too.
Now, complete the practice to make sure you got it.
