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.

Is All information on a line graph is as precise as the information in the data table?
the answer is no some times the information on the line graph is not as accurate as the info on the data table.
over 75% of the circle.
What is ordered value bar graph?
An ordered value bar graph is a value bar graph in which data values are arranged in increasing (or decreasing) order of length.
What is a line graph in the coordinate plane that has no breaks in it?
It is a continuous line graph.
What is the difference between a line graph and a linear equation?
A linear equation, when plotted, must be a straight line. Such a restriction does not apply to a line graph.
y = ax2 + bx +c, where a is non-zero gives a line graph in the shape of a parabola. It is a quadratic graph, not linear. Similarly, there are line graphs for other polynomials, power or exponential functions, logarithmic or trigonometric functions, or any combination of them.
The earliest known pie chart is generally credited to William Playfair's Statistical Breviary of 1801, where two such graphs are used according to WikiPedia Some sources say Florence Nightingale invented the Pie Chart in 1857, but in fact even the Florence Nightingale museum admits she did not. She was an amazing person, but unfortunately not the inventor of the pie chart.
What are the disadvantages of a stacked bar graph?
You can only make a stacked bar graph if one of the groups is always smaller than the other.
Otherwise one bar might go right over the other one.
* * * * *
The above disadvantage does not apply to stacked bars where the bar for each variable is stacked on top of other bars. The main disadvantage is that it becomes increasingly difficult to see changes in all but the variable that is at the bottom of the stack (and so has a fixed bottom line).
What is the difference between a double bar graph and a bar graph?
The difference between a bar graph and a double bar graph is...... A bar graph displays one set of data, and a double bar graph compares two different sets of information/data.So should have a key.
When is a bar graph and line graph used?
A bar graph is best when the data are divided among time periods or other criteria, such as the number of U.S. House members per U.S. state.
A line graph is best for data that are constantly changing, such as the outdoor temperature of a city.
Why is a pie chart called a pie chart and not a cake chart?
A pie chart is called a pie chart because it looks like a piece of pie cut into sections... It ISN'T called a cake chart, because a cake chart would be to controversial. - iow (in other words) - a cake can be multi-layered, or it can have fancy icing, or even small figures or toys... Where as a pie is almost always flat (depending on the pie), never has fancy icing, and is never multi-layered...
To put it another way, a cake chart would be hard to explain, where as a pie chart is what everyone is familiar with, and almost no explaining is required... Put's less pressure on everyone to just pie chart.
Which type of graph would best show the number of books in each bedroom?
A bar chart for a small number of bedrooms. A frequency polygon (with grouped data) for many rooms - for example in a student dormitory.
Are Pictographs Similar to Bar Graphs?
kind of although if you are dealing with large numbers a bar graph is better pictographs are easier to follow and understand
What are the units on the vertical axis of a line graph?
The units are whatever you make them! It helps, though if the units are the same on the x-axis (horizontal axis) as well. Unless of course you are skipping from zero to some large number before you start your graph.
Anyway, you can make each line one unit, or you can make each line 5 units, or whatever you want! Depends on what you're graphing, but usually for a straight line, you use units of 1
Here's an idea, the different stages of mitosis have different amounts of time they spend in each. By counting the total number of cells and categorizing which stage each is in, you can then divide the number of cells in each stage by the total number of cells to infer the length of time each stage takes. Most likely metaphase is longest if I remember correctly.
What does a speed vs time graph look like?
It is a line chart which usually starts at the origin, goes up in the first quadrant. It may return to the horizontal axis.
