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.

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.

How do you work out the frequency for a histogram?

Frequency Density multiplied by the class width

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 not, bar graph.

What is a synonym for pictograph?

a character that stands for a object or writing such as a speaker

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.

What type of data is best displayed graphically on a line graph?

first a line graph shows data that is continuous so something that like weather or rain fall

Which data would be best analyzed and communicated using a histogram?

What is the difference between double bar graph and double line graph?

A double bar graph is a graph that uses pairs of bars to compare and show the relationship between data. However, a double line graph is a grid graph that uses pairs of lines to compare and show the relationship between data.

Why do you use a line graph and bar graph?

A line graph is most often used to show the passage of time, and the points are placed in a specific order to show the change from one point to the next. A bar graph displays a set of statistics with no particular order to them.

What kind of information is on a pie graph?

Any information where many parts make up a whole, such as if you were to find how many apples, oranges, or bananas there were in a bag of fruits, the bag of fruits would be the whole and apples, oranges, and bananas would be the sections of the graph

Why do the bars touch in histograms?

The intervals that the bars represent are touching each other.

How could a line graph be misleading?

It could skip numbers, such as if you are counting by 3's (3,6,9,12,15) then it could have wrong numbers, and there could also be other misleading stuff too.

+++

It could be misleading if the values themselves are incorrect, or if the line is a best-fit trace drawn erroneously, perhaps on a graph of points that genuinely do not really follow a discreet numerical law.

What 4 things do a line graph need?

title

axis labels

units

don't know any more but I hope that helps....

What is an exploded pie chart?

An exploded pie chart is a pie chart with one (or more) of the segments pulled away from the centre.

What is a divergent bar graph?

A graph with a data spread which is both positive and negative can be displayed on a divergent bar graph. These could be constructed on either the x or y axis. Most of you will have seen such a graph which has been drawn on a population pyramid.

What type of data would you use a bar graph to show?

Bar graphs are an excellent way to show overall trends. Example sales for the months of the year - with y-axis "Amount of Sales in Dollar Amounts" and x-axis "Months of the Year" or visa vera. The bar can be either vertically or horizontally. Bar graphs are usually a simple chart.
