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.

Why is a double line graph used?
Double lined graphs are used to compare two different variables.
For example:
The x-axis could contain years.
The y-axis could contain an amount for a population.
The points on the graphs could contain men and women.
A pie chart is based on percentages, where each slice of the pie represents the percentage of the entire pie, adding up 100% total.
A pie chart can be drawn using a pen and paper.
first make a circle then draw little triangles that make up ur percent the bigger the percewnt the bigger the slice the smaller the percent the smaller the slice
What advantages does a histogram have over a frequency distribution?
Dunno but would be helpful if someone knew cause Im in maths and need to know
Histogram
Do picture graphs and bar graphs show you patterns over time explain?
These graphs CAN show you patterns over time as long as one of your axes shows time (usually the x axis). However it is easier to see trends over time if you use a line graph, and this is more common.
When is it the best time to use a bar graph?
I use a bar graph to represent my favorite pies, and a pie graph to represent my favorite bars.
How do you change a column chart ao a pie chart?
Not all column charts can be converted to pie charts. It can only be done if the column chart has a single series, as a pie chart can only have one series. If the column chart has more than one series, only one series will be shown when it becomes a pie chart. If the column chart has a single series then going to the Chart menu and choosing Chart type will enable you to change it.
How is a scatter plot different from a line graph?
Scatter plots show how much one variable is affected by another,A graph that uses points connected by lines to show how something changes in value
What information is given in a line graph?
It depends on the two (or more) variables that are plotted on the graph.
Why does it make sense to put lines in the plot of a line graph?
A line allows you to better visualize the trend of the graph.
Anyone of them is fine. It doesn't really matter.
Why don't all the points fall exactly on the curved line on a line graph?
You don't say what the curved line is so it is impossible to say. Is it a case of insufficient accuracy of measurement?
Do double bar graphs have mean and mode?
Yes they do. All graphs have a mean and a mode. The difference with a double bar graph is that you have to find the mean and mode separately with each different thing you are measuring
What is the answer and workings for this equation on plotting straight-line graphs y equals -x?
y = -x
The slope of the line is -1, and its y-intercept is zero.
The graph is a 45-degree line, sloping down to the right, and passing through the origin.
The 'x' and 'y' coordinates of every point are the same number, but every point has one
positive coordinate and one negative coordinate. That's exactly what the equation is
saying.
How do you find a median in a line graph?
With great difficulty. There is no real way of discerning how many observations there are or how far apart they are along the horizontal axis.
What is the benefits of bar graphs?
the befits of a bar graph is a way to keep you data but using bars . there can be a horizontal bar which is a bar going horizontally or a vertical bar which is a bar going vertically . a bar need a title and numbers going up the y axis and numbers or names going across the x axis .
