8. What do you call the list of fruits made by the pupils?
It is called data. The data gathered is what we called
collection of data.
How can we get information?
By conducting a survey, by asking same set of questions to

14. From the tally chart or tabular form, we can also
present this in a form of a bar graph.
Bar graphs are representation of data,
quantities or numbers using bars or strips.
These are used to compare and contrast
numbers, frequencies or other
measures of distinct categories of
data. They have an x-axis (horizontal) and
yaxis (vertical) .
16. 1. Vertical bar graph.
A graph that visually displays data using vertical bars
going up from the bottom, whose lengths are proportional
to quantities they represent. It can be used when one axis
cannot have a numerical scale.
17. 1. What is the title of the bar graph?
2. What information is placed along the horizontal axis?
3. How about on vertical axis?
18. 2. Horizontal bar graphs
Represent the data horizontally. It is a graph whose bars
are drawn horizontally. The data categories are shown on
the vertical axis and the data values are shown on the
horizontal axis. This is an example of horizontal bar graph
19. 1. Which fruit has
the most number?
2. Which fruit has
the least number?
3. What is the
difference between
cherry and
banana?
21. Construct a vertical bar graph with the given data
below.
