How do you show 30 percent on a pie chart?
A segcot whose angular measure (at the centre) is 360*30/100 = 108 degrees.
Who does the bar council represent?
Bar council represents bars and pubs. They are there to make sure that all places have their ABC licenses and are doing business within the correct guidlines.
Do the bars have to touch in a histogram?
Usually yes, although it is possible for there to be bars of 0 height which may give the appearance of gaps betwwen bars.
Why on a line graph do all the points not fit exactly on the line?
because they are annoying like that.
the reason it's called a line graph is because you join up the dots with a line.
or you can leave the dots unjoined (a scatter graph) and draw a line of best fit.
this is a line that doesn't touch any of the dots, but has a roughly equal amount on each side. there is no right or wrong line of best fit, but you cant have, say, 4 dots on one side and 1 on the other. the point of 'lines of best fit' are to show roughly where the dots go - the pattern of the data.
HOWEVER, if drawing a line of best fit, you must first identify, then discredit any ANOMALIES, which are results of the data that are very different to the other answers; they do not fit into the pattern.
How do you get median and mode from histogram?
You can't. You can get the median and mode from the data set, but not the histogram itself.
When do you use line graphs in maths?
When form example showing the difference in each year of the increase of carbon dioxide. Does that answer your question or do i have to explain further??
What is the purpose of key for double-bar graph?
To Tell whether which is which.
For example let's say you have a red bar and blue bar, how are people going to know which is which? So that's the purpose of the key.
Why is it important to label a bar graph?
So you know what your talking about and what's in it so you can figure out how much is what and this is coming from a 4th grader.
When you draw the bar on a bar graph do they go horiztonal or vertical?
You can do either. Depending on how they look and how many data points you have.
Why the histogram equalization operation is idempotent?
yes,the histogram equalization operation is idempotent
Do you call a pie graph a pie graph or a pie chart?
They are the same thing, so it really doesn't matter. I usually say graph, but whatever is easiest to you.
Pie chart it is used for percents of a whole, no time included.
What is the importance pie chart?
Pie charts help people view statistics conveniently and, more often than not, with nice colors too. That way one doesn't have to keep explaining the statistics, one look at the pie chart and someone can identify the info.
What is one percent of the pie in a pie chart?
Still 1%.
Open Microsoft Excel. In A1 type "1%" and in A2 type "99%." Select both of them (click on A1 and press SHIFT +DOWN) and click "Insert" -> "Chart..." -> "Pie" and "Finish." The smaller slice is 1%.
What graph would be best for comparing?
If they things you are comparing part of a whole, pie graph.
If not, bar graph.
Does a pie chart have a horizontal axis?
No. Nor a vertical axis. The main measure is the angular one - although a secondary measure can be introduced by changing the size of the pie. For example a small pie for when the total was small and a larger pie for when the total was large. However, this is often misleading since it is not always made clear whether the radius or the area is proportional to the total. It should be the area but people are not very good at judging differences in circular areas.
