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.

For an ordinary bar graph you need two variables, the dependent variable being numerical. You need at least two observations - unless you want a bar graph that serves no purpose.
You could have more than one dependent variables for a stacked or grouped bar graph.
What is the definition for a single bar graph?
umm the defintion would be like jupiter with giant elephants on it and pigs eating hot dogs
What is the key on a pie chart?
Here are two explanations that are both correct. Use whichever works for you:
- Its basically the bit, usually in the corner, that explains what each colour (or whatever is being used) on the pie chart represents.
- So, you might have a pie chart that is divided into sections, with each section having a different colour. The key is often a short list of small squares that are in all the colours on the pie chart. Besides these squares will be the thing that their colour represents on the pie chart.
Why is it appropriate to display categorical data in a bar graph but not a line graph?
Usually a bar graph is used to display data for a number of different items (such as a grocery store could have a sales graph displaying sales for produce, dairy, meat, etc.), while a line graph is used to show a trend (like sales volume over time).
Distinguish between histogram and historigram with example?
Type your anshistorigram
a term used to denote a graph of a time series with the value of the series as ordinate against time as abscissa Category: Mathematicswer here...
What type of data should you use a line graph to display?
How Was The Temperature Of Th Week or Month !
What are disadvantages of bar graph?
- Hard to quantify partial icons
Icons must be of consistent size
Best for only 2-6 categories
Very simplistic
Not as visually appealing
Best for under 50 data values
Needs small range of data
No exact numerical data
Hard to compare 2 data sets
some disadvantages u can find,
can use only with discrete data n also the graph categories can be reordered to emphasize some effects over that
A histogram does not have gaps in between the bars because the intervals are connected i.e. 0-99, 100-199, 200-299.
Why do people use a pie chart?
To show statistics, it was first used by Florence Nightingale to show the British government the statistics of the amount of hospital patients dying unnecessarily
Where does pictograph used in real life?
pictographs can be used in different types of business's to provide data for what they are going to create or work on (it actually depends on the type of business because if it was a manufacturing business the data would help them know how the would like to build their products).
Why is a legend important to understand a bar graph?
A legend is important because it tells about the scale of the bar graph and it also explains the colours in the graph. it becomes very easy to make or understand the bar graph
What is the difference between a scatter plot and a line graph?
Scatter plots and Line graphs have similarities in that they both use an X-Y axis.
But a line graph has a line or curve to describe a formula like Y=2X+5, a Scatter plot is a collection of X-Y coordinates that have no real formula due to real life uncertainties (Heisenberg), but, once plotted, can provide a clue to a single formula.
How do you find the range of a bar graph?
Subtract the greatest range by the least and you have your answer.
What is the independent variable in a line graph?
Independent variable is the one to be investigated; the one that will be changed to get results.
If you are still finding it too hard just keep this in your mind-- Independent variables answer the question "What do I change?" in an experiment. Dependent variables answer the question "What do I observe?"!
What is an axis in an independent variable in a Line graph?
Typically the horizontal axis represents the independent variable.
What should a bar graph have between the bars?
Well nothing just space so people can see the graph easily. Don't forget ur y-axis and x-axis!
