Describe, interpret and/or answer questions based on data shown in tables, charts, bar graphs and pictographs.
Did You Know?
Bar graphs and pictographs are types of graphs that graphically show and compare
data. You can look at the graph to
more easily interpret or answer questions
about the data.
Check What You Know First
Mary collected coins in a jar. She wanted to make a graph to
show the number of different types of coins
she had. She decided to
make the bar graph below to graphically show her data.
Look at the vertical bar graph to interpret the data and answer the following questions.
How many types of coins did Mary collect?
What are the names of the coins that Mary collected?
What is the title of Mary’s
graph?
What coin has the largest number?
How many pennies are in the jar?
How do you know this coin has the largest number?
What coin has the smallest number?
How many dimes are in the jar?
How do you know this coin has the smallest number?
Key Vocabulary
A bar graph is a graph that uses bars to show data.
A vertical bar graph is bar graph in which the bars go up from bottom to top.
A horizontal bar graph is a bar graph in which the bars go across from left to right.
A line graph is a graph that uses a line to show how something changes over time.
A pictograph is a graph that uses pictures to show and compare information.
A range is the difference between the greatest number and the least number in a set of data.
A scale is a series of numbers placed at fixed distances
on a graph to help label the graph and assist you in
reading the number each
bar shows.
An interval is the distance between two numbers on the scale of a graph.
A key is the part of a graph that explains the symbols or
pictures used. It indicates how many each symbol or picture
in the pictograph
stands for.
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
Looking at the bar graph should have assisted you in answering
the questions. A bar
graph is a graph that uses
bars to show data. Showing
the data graphically should help a person interpret the data more easily. You
can illustrate
data in a vertical bar graph or a horizontal bar graph. A vertical
bar graph is bar graph in which the bars go up
from
bottom to top. This is the type of bar graph used in the Check What
You Know section. A horizontal bar graph is
a bar graph in which the bars go across from left to right.
Below is an example of a vertical bar graph and a horizontal
bar graph. They look different, but illustrate the
same information. The
information below the bar graphs tells how to read each type of bar graph.
Looking at either bar graph, you can see the title (Coins In A Jar) at
the top. The sides of the graph are also labeled.
One side has the scale
of numbers used. A scale is
a series of numbers placed at fixed distances on a graph to help label
the
graph and assist you in reading the number each bar shows. A scale always
starts with 0. In this graph, the
scale goes from 0 to 12. The
top value of the scale when making a bar graph should be greater than the greatest
value
of the data. The scale side is labeled Number of Coins.
An interval is also selected on a bar graph. An interval is
the distance between two numbers on the scale of a graph or the
difference
between two numbers on the scale. The interval is 2. You
are counting by 2’s on the bar graph. (0, 2, 4, 6, 8, 10, 12)
The other side of the bar graph has a label entitled Coin with a list of coins
used. The four types of coins that were collected
include quarters,
dimes, nickels and pennies. These types of coins are labeled
on the bar graph.
You can quickly tell which coins there are the most of and the least of by
looking at the bars. The coins with the largest number
collected
are the pennies. You can tell this by looking the chart.
The bar for
pennies is the highest/longest.
The coins with the smallest number collected are the dimes. When you look at the chart, the bar for dimes is the lowest/shortest.
To find out specifically how many coins there are for each
group, you can look at the scale side with the numbers. You follow
the edge of the
bar to the number on the scale side. There are 4 dimes and 12 pennies. There
are also 6 quarters and 8 nickels.
Data can also be graphically shown on a pictograph. A pictograph is
a graph that uses symbols or pictures to show and
compare information. A
pictograph should have a title. Each row should be labeled with a name. A
key should also be created.
A key is the part of a graph
that explains the symbols or pictures used. It indicates how many each symbol
or picture in the
pictograph stands for.
Look at an example of a pictogram:
Check What You Know About Using a Pictograph
Use the pictograph above to answer the following questions.
worth?
Which animal is there the most of?
Which animal is there the least of?
How many monkeys are there?
How many elephants are there?
List the animals from greatest number to the least?
Learn About The Pictograph Now
A pictograph uses pictures or symbols to show data. The key shows
you what each picture represents. In the key in
this pictograph, each
star is equal to 5 animals. To find out how many of each animal there
are, you can
multiply 5 by the number of stars. For example, there are
30 monkeys. You multiply 5 x 6 to get 30 monkeys.
By simply looking
at the pictograph, you can tell that the monkeys represent the most number
of animals. There
are 6 stars, which is the greatest number of stars
beside the label of the monkey. Looking at the pictograph again,
you
can see there are only 2 stars beside the label of the elephant. This
shows that the least number of animals is
the elephant. To figure out
how many elephants there are you multiply 5 x 2 to get 10.
More Practice with the Pictograph and the Bar Graph
Use the pictograph and the bar graph that you used before to answer the following additional questions.
How many lions are there?
How many giraffes are there?
How many monkeys are there?
How many bear are there?
What is the total numbers of animals in the zoo?
(Hint- First multiply
each star by 5 and figure out the number of individual animals. Then add up
the number of
the individual animals to get the final sum.)
The bars go up in what kind of bar graph?
The bars go across from left to right in what kind of bar
graph?
How many quarters are in the jar?
How many nickels are in the jar?
How many more pennies are there than nickels?
How many more quarters are there than dimes?
What is the total number of coins in the jar?
