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.

How do you make a pie chart without using excel?
Use a calculator, protractor and ruler, along with colour pencils or similar.
What is a bar graphs weakness?
The main problem with bar graphs are that they can only be used when all values for x are discrete and have equal weight. For instance, if we wanted to do a graph of how many people liked different colours, we could do a bar graph. Because the x axis would have values "blue" "yellow" "green" etc. and these would be discrete answers. If we wanted to do a graph of people's weight vs their height, you could not use a bar graph. This is because height would not fit into neat categories like colour does.
When is it best to use a pie chart instead of a bar chart?
when you want to show percents................... 100% correct !
100+75+50 = 225
Explanation:
1st bar is twice of the second bar 100%
2nd bar is 75% of the first bar
3rd bar is 50% middle of first and 2nd bar
Can a steep curve in a line graph indicate a rapid or a slow rate of change?
its going to be a rapid rate of change because it changes fast. a slow rate would be a steady or a smaller curve
it is time consuming because it involves cumbersome calculations
Why is a bar graph better to use than a circle or pie graph?
A pie graph is percentages and is harder to read because sometimes it doesn't show the %
A bar graph is more acurate because it gives you numbers and more info
When would you use a histogram?
A histogram is used to analyze a distribution of data. It look like a graph and can be used in many formats - the most popular may be in Photography, showing the distribution of shadows and light in a visual representation.
Where to create a pictograph online?
i don't know about online but i do know that Microsoft exel can create pictographs
How could you plot more than one dependent variable on a line graph?
you could use different line styles (a solid or dotted line) or you can use different colored lines.
How does a line graph make it easy to see changes over time?
It helps you see changes over time, because you can look at it and see when the line goes up for a period of time, the unit on the Y axis is getting higher, and when it goes down, it's getting lower.
it summarise data visually,it is appealing and avoid complex computations,is easy to understand.
What does a trend mean on a line graph?
It is a description of the Slope of the line with respect to the two variables you are plotting. In Statistics, you may be plotting AGE versus Car Mileage and a line drawn through the data is the Trend Line.
Are angles used in Pie Charts?
Yes. Angles are used to draw pie charts so that each portion has an equal amount of the circle by the total.
try sqrt(N) where N represents the number of observations you have...
What are the meaning of bar graphs line graphs pie graphs?
aaa Bar Graph - A graph consisting of parallel, usually vertical bars or rectangles with lengths proportional to the frequency with which specified quantities occur in a set of data. Also called bar chart. A bar chart or bar graph is a chart with rectangular bars with lengths proportional to the values that they represent. Bar charts are used for comparing two or more values. The bars can be horizontally or vertically oriented. Sometimes a stretched graphic is used instead of a solid bar.
Pie Graphs? or Pie Charts - A pie chart (or a circle graph) is a circular chart divided into sectors, illustrating relative magnitudes or frequences or percents. In a pie chart, the arc length of each sector (and consequently its central angle and area), is proportional to the quantity it represents. Together, the sectors create a full disk. It is named for its resemblance to a pie which has been sliced.
Line Graphs - The line graph is also sometimes called the edge graph, the adjoint graph, the interchange graph, or the derived graph of X A line chart or line graphis a type of graph created by connecting a series of data points together with a line. A line chart is a basic type of chart common in many fields. It is an extension of a scatter graph, and is created by connecting a series of points that represent individual measurements with line segments. A line chart is often used to visualize a trend in data over intervals of time, thus the line is often drawn chronologically
(mathematics) A graph in which successive points representing the value of a variable at selected values of the independent variable are connected by straight lines.
