Graphs
Graphs often collect a set of data in a group of people. There are many kinds of graphs: pie charts (circle charts), bar graphs, line graphs, data tables, pictographs, flow charts, histograms, etc.

Whatever information is in the data in a clear and honest way.
How can a line graph help you investigate the relationship between two sets of data?
The general shape of the line indicates whether the relationship is linear, quadratic, polynomial, power, inverse etc. It will also help determine whether the relationship remains the same over the whole domain or changes.
The scatter of the observations about a line gives a measure of the variation in the observations about the values that might be expected from the line graph.
Do points plotted on a line graph represent the actual data recorded by an experiment?
Yes, it shows the data in a different way
What situation you have you use a pie graph?
A pie graph is used when representing portions of a whole.
How do line graphs help investigate the relationship between two sets of data?

What it the horizantle axis for a bar graph?
The horizontal (not horizantle) axis is usually the categories.
How would you graph -3.4 on a number line graph?
On a number line, the positive numbers extend to the right of zero, and the negative numbers extend to the left of zero. So -3.4 is 3.4 to the left of zero.
increasing the interval would decreasing the degrees of accuracy of the graph, optically the line seem flatter
How can you identify continuous variables on a line graph?
With great difficulty. This is because if the variable is recorded by people, it will be rounded. That process will make it discrete - even if the underlying variable is continuous.
For example, time is a continuous variable, but time is normally recorded in seconds. At track events it may be measured in hundredths of seconds and in some labs in much smaller units. Nevertheless it will always be in discrete "chunks".
What is a scatter plot line graph used for?
Scatter plot line graphs are used:
- In research to see trends
- by Actuaries to predict insurance rates
- by economist to predict the economy
The general idea is to derive a trend or general theme for a series of points of data.
What are the x and y axis for on a bar graph?
One axis contains the data sequence, whether categories, time, etc.
The other axis is used to represent the magnitude of each datum in the sequence.
For example, a bar graph of annual rainfall over 10 years from 2000-2009 might have an X axis labeled for each year and a Y axis indicating inches of rain fall.
The bars in the graph would then stretch up over each year value to the level on the Y axis representing the amount of rain that fell that year.
Why are points in a line graph connected but not in a bar graph?
i asked my dad and he didn't know but i think its because bar charts are never connected
How to estimate the average on a line graph?
You cannot, because you will not know whether the observations are evenly spaced.
What is difference between a bar graph circle graph and line graph and when would you use them?
I'm in sixth grade and I use circle graphs in social studies and bar and line graphs in science
How can a line graph be used to describe a relationship?
It depends on what kind of relationship. If it's business wise, then it can describe a relationship between products and sales. If it is mathematics wise, then it can be used to describe a relationship by showing the differences and similarities of different products.
