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.

Why was Sandy's choice of a line graph a good one for this set of data?
It's impossible to tell unless we have both the graph and the set of data.
Why are bar graphs used for certain types of data?
A bar graph is used to show different totals in different categories.
What is two thirds on a pie graph?
A full pie graph is 360 degrees.
2/3 of that = 240 degrees.
(what is left over is the other one-third = 120 degrees)
What type of graph do you use when you are comparing things that is not a double bar graph?
you would use a line graph
Scatter Plot.
How do you find the x-axis on a line graph?
The x-axis is the horizontal line that correlates with the vertical y-axis.
How is it easy to read a pictograph?
Pictographs use pictures with a key to help you read it easily instead of reading a bunch of words and numbers.
What is the advantage of examining the histogram instead of the frequency distribution?
A histogram efficiently presents the same information as the frequency distribution in one visual image and gives all the relevant details in an intuitive format (center, variation, distribution shape, outlier, and time = CVDOT).
Why are the lowest numbers at the top of a line graph rather than the bottom?
They usually are not at the top.
What are the advantages and disadvantages using broken line graph?
A broken line graph is useful when there is a large gap between the values of one of the variables.
In the context of graphs over time, this may happen for many reasons. Possible causes are that the data were not available for a period (eg during war), or the method of collection was changed. Nevertheless, if these breaks are explained, the graph can provide indications of long term trends.
The disadvantage is that data on either side of the break, may not be comparable, even with the explanations, and the naive or careless user may be misled.
What is the best graph for numerical information?
The best graph for numerical information will depend on what you want to present. The linear graph, bar and the pie graph are some of the best graphs to present numerical data.
Idk how to explain really. Just draw a line going up 2 and from the bottom end make the 5 then sort of go back 4 on the other side
Which values would a scientist NOT use a graph to compare?
A graph would not be useful to illustrate the times between eclipses, or the comparative shapes of airfoils. Graphs only illustrate numerical information in comparison with other similar values.
What information can you determine from a bar graph that you cannot determine from a circle graph?
asha
Why would you use a pie graph instead of a line graph?
pie graphs show volume and are good for showing the relationship of size.
line graphs are good for showing trends which can lead to predictions.
What if the y-coordinate of a point on the line graph if the x-coordinate is 8?
depends how much coffee it had this morning...
How is a bar graph and a pictograph alike?
Bar graph and pictograp are ploted on a horizontal line and in a positive quadrate
What does peak mean when using line graphs?
The peak of any graph is the highest point (usually in the y direction). The peak is the maximum value.
What does the height of a bar in a histogram represent?
The frequency density. That is, the frequency divided by the class width.
