A band of 1 SD will represents about 68% confidence whereas 2 SD represents around 95%. Since the latter is often used for hypothesis testing, it may be better to use 2 SD.
You cannot because the median of a distribution is not related to its standard deviation.
You cannot. There is no information about the distribution, or even what the graph is meant to display!
Whomever placed this question should learn how to use punctuation. The actual question should be: For business data, what is the most accurate visual display? a. table b. graph c. standard deviation d. bar chart e. median chart?
The Gaussian "Bell" Curve has probability density function: f(x)= exp{-((x-mu)2/(2*sigma2)) } / (sigma*sqrt(2*pi)) where mu=mean & sigma=standard deviation
A point can represent a piece of data or an (x,y) value.
the best graph to use to represent fractions is a pie graph, that is if all the fractions denominators are the same...
Tables and graph represent relations by showing the distribution of occurrence.
A graph about masses and volumes would represent density.
I use a bar graph to represent my favorite pies, and a pie graph to represent my favorite bars.
a picto graph is a graph that shows pictures to represent numbers
Suppose you plotted the same pairs of variables from two data sets on the same scattter plot, perhaps representing the two data sets in distinct colours. Then if the data sets differed sufficiently in standard deviation you would notice greater scatter or spread in one of them.
Draw a list of pictures about what you had to do kind of like instructions and there is you chart
