Analyze data shown on tables, charts, bar graphs or pictographs using
the concepts of largest, smallest, most often, least
often and middle.
Did You Know?
Organizing data in a chart or graph enables you to draw conclusions and make predictions.
Check What You Know First
Mary was in a class with 20 students. She wrote a question to find
the class’s favorite color.
Look at the following results of a survey
and answer the questions.
What color was chosen most often as the favorite?
What was the largest number of students who voted for a particular color?
If you ordered the numbers in the frequency chart from least to greatest,
what corresponding color would
be in the middle of choices?
What was the smallest number of students who voted for a
particular color?
What color was chosen least often as a favorite?
Key Vocabulary
An experiment is a test that is done in order to find out something.
An observation is when you watch an event taking place and record what you see.
A survey is a question or set of questions that a group of people are asked.
Results are the answers from a survey.
Outcomes are the possible results of an experiment.
Data is information that is collected on something such as people or things.
To classify is to group pieces of data according to how they
are the same, for example, you can classify data
by size, color or shape.
A tally chart is a table that uses tally marks to record data.
A frequency table is a table that uses numbers to record data.
Learn About It Now
Data is information
on something such as people or things. Data
can be collected by conducting an experiment,
doing an observation or
conducting a survey.
In the example, a student wanted to find out some information. She was
interested in collecting data on her
class’s favorite color. She
conducted a survey by asking the class a question. The question was: What
is your
favorite color? Once she obtained the results or
answers from the survey, she needed a way to organize
and display the data. The
possible results from an experiment are called outcomes.
A tally chart is one way to record and organize data. You
use tally marks to record the information.
Then you count the tallies
to write the frequency of the numbers in a frequency table.
She discovered that the most often chosen color was red. Her
chart revealed that red was the most favorite
color in this class. In
her class of 20, the largest number of students picking one
color was 6. There were 6
students who liked red the most. The least
often color chosen was blue which means that blue was the least
favorite
color for this class. The smallest number of students
picking a color was 2. Only 2 students selected
blue as their favorite
color. By making a tally chart and frequency table, Mary was able to
organize the collected data.
Now she could view the information more
easily making the data more understandable.
Let’s Try More Practice With This Experiment
Susan fills a bag with 20 marbles. There are 7 blue, 2 green 4 yellow
and 7 red marbles.
She pulls a marble from the bag. She records the color
on her tally chart.
She then puts the marble back in the bag and pulls
another marble from the bag.
She pulls a marble from the bag 10 times.
Below
is a list of outcomes for the 10 pulls and Susan’s tally chart.
Use Susan’s tally table to answer the questions.
What are the possible outcomes?
(Hint – Name all the colors Susan could pull. Separate
color words with a comma.)
What color did she pull the least often?
What color did she pull the most often?
How many times did she do the experiment?
(Hint-What is the total of either
the tallies or the frequency?)
What is the largest number of times she pulled a marble of 1 color?
What is the smallest number of times she pulled a marble of 1 color?
There was one colored marble pulled the most often. There was one colored
marble pulled the least often.
What are the colors of the marbles that
were in the middle of the number of times pulled?
