We use possessive pronouns to refer to a specific person/people or thing/things (the "antecedent") belonging to a person/people (and sometimes belonging to an animal/animals or thing/things).
1. Forms of Possessive Pronouns and Adjectives

1st plural ours our
3rd plural theirs their
2. Using Possessive Pronouns and Adjectives
A possessive pronoun is used instead of a noun:
Julie's car is red. Mine is blue.
A possessive adjective is usually used to describe a noun, and it comes before it, like other adjectives:
My car is bigger than her car.
Thereare no apostrophes in possessive pronouns and adjectives.
The dog wagged its tail.
“It's” is not a possessive pronoun or adjective — it means “it is”:
It's not my dog.
What are the units of measurement for volume?
The volume of any solid, liquid, gas, plasma, vacuum or theoretical object is how muchthree-dimensional space it occupies, often quantified numerically.
The volume can be measured in cubic meters, cubic centimeters, or liters. The units of the three-dimensional volume depend on the units of length - if the lengths are in meters, the volume will be in cubic meters, etc.
To measure a square or cube: Volume = length times width times height.
Bar Graph Comparisons
After completing this unit you should be able to:
• Identify the bar graph title.
• Identify labels for the bar graph axes.
• Identify information given by a designated bar• Make statements about data trends from a bar graph.
What is a Bar Graph?
A bar graph is a visual display used to compare the amounts or frequency of occurrence of different characteristics of data. This type of display allows us to:
• compare groups of data, and
• to make generalizations about the data quickly.
This unit will introduce basic bar graphs, how to read bar graphs. Anexample of a bar graph is given on the right.
When reading a bar graph there are several things we must pay attention to: the graph title, two axes, including axes labels and scale, and the bars. Since bar graphs are used to graph frequencies or amounts of data in discrete groups, we will need to determine which axis is the grouped data axis, as well as what the specific groups are, and which isthe frequency axis.

The height of the bars are particularly important since they give us information about specific data.
Parts of a Bar Graph
Now let's look at the components of a bar graph individually. There is a lot of information in this section so you may wish to jot down some short notes to yourself.
• Graph Title--The graph title givesan overview of the information being presented in the graph. The title is given at the top of the graph.
• Axes and their labels--Each graph has two axes. The axes labels tell us what information is presented on each axis. One axis represents data groups, the other represents the amounts or frequency of data groups.
• Grouped Data Axis--The grouped data axis is always at the base of thebars. This axis displays the type of data being graphed.
• Frequency Data Axis--The frequency axis has a scale that is a measure of
the frequency or amounts of the different data groups.
• Axes Scale-- Scale is the range of values being presented along the
• Bars--The bars are rectangular blocks that can have their base at either
vertical axis or horizontal...
