2. Organizing Data by:
 Using Line Plots
 Describing Data (mean, median,mode,
and range)
 Making Charts or Graphs(bar
graphs,circle graphs,pictographs,line
graphs)

3. Line Plots
 Line plots are diagrams that organize
data on a number line
 If your data is numerical, one way to
show it would be with a line plot

4. Here’s a way to make a line
plot.
 Find the least and the greatest numbers
in your set of data for your line plot.
 Choose a sequence that will fit your
data.( arrange the numbers by 2’s, 5’s
etc.what ever works best for your data)
 Put an x on the line plot to represent
your data
 Write a title for your line plot.

5. Describing data
 Mean
 Median
 Mode
 Range

6. Mean/Average
 To find the mean or
average of a set of
data you first :
 Add the numbers
 Count the number of
data
 Divide the total of
the numbers by the
number of data.
 6,4,6,5,7,7,4,9=48
 There are 8 sets of
data
 Divide 48 by 8 = 6
 To check, 8 x 6= 48

7. Median
 The median number of
a set of data is the
number found in the
middle.
 Arrange your data in
order from least to
greatest to find the
middle number.
Sometimes you will
have two middle
numbers.
 4
 4
 5
 6
 6
 7
 7
 9

8. Mode
 The mode of a set of data is the number
that occurs most often in the data.
 You may have more than one mode.
 4,6, and 7 are your modes in this set of
data.

9. Range
 The range of a set of data is found by
subtracting the least number from the
greatest number.
 9 – 4 = 5
 In this set of data the range is from 4 to
9 with the exact range of 5.

 Bar graphs are
another way to show
data.
 Double bar graphs
help you to compare
data.

11. Line graphs
 Line graphs are
good for showing
changes in data
over time when
working with dates.
 Double line graphs
can help you show
even more data and
compare data.

12. Circle graphs/Pie Charts
 Circle or pie charts
are another way to
show data, and
compare data to
percentages or
fractions of a whole.

13. Pictographs
 Pictographs are
often used to show
data in newspapers
and magazines
because they get
your attention.
 Each picture
represents a specific
number of data.

14. In conclusion
 Organizing data makes it easier to read
and understand.
 Using graphs and charts helps to get
the attention of your audience
 Charts, line plots and graphs are ways
to organize data so it is useful to you.
 Comparing data is easier when it is
clear and specific.
