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.

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.
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.
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.

You use line graphs to see how something changes over a period of time , Such as weeks,days,months,or even years . We use line graphs alot!
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.
How are a bar graph and line graph different?
a bar graph is like a line grapgh but the difference of they are the bar graph show horizontal and line graph shown vertical.. think logic..^_^
Histograms are relatively similar to line plots;
A bar graph of a frequency distribution in which the widths of the bars are proportional to the classes into which the variable has been divided and the heights of the bars are proportional to the class frequencies.noun
Ancient Egyptians used pictographs for writing This system of writing they developed is called?
Well, we will never know what they called it, but now we call them Heirogylphs or Heiroglyphics.
How do you create a percentage frequency histogram?
what is the difference between a regular histogram and a percent frequency polygon
Which way do the x-axis and the y-axis go on a bar graph?
The X axis is the horizontal line. The Y axis is the vertical line.
What is a data table used for?
A data table is used to organize and display information that are gathered.
