Answer:
Option D, Standard deviation
Explanation:
The error bars in a graph depict how the data varies from each other with in a data set. Or in other words it shows the irregularities and uncertainties in the data. A standard error data graph shows how the values in a data set vary from the mean value.
Standards error value is equal to
[tex]SD = \frac{\sqrt{(X -M)^_{2} } }{N-1} \\\\SE = \frac{SD}{\sqrt{N} }[/tex]
Where SE is standards error
SD is standard deviation
M is the mean value of data set
X is all numerical value of a given data set
N is the number of values in a data set
Hence, option D is correct.
