Question

Which quantity is used to generate the error bars in a graph? Range. Median. Linear correlation. Standard deviation.

Answer 1

Standard deviation, really hope this helps you out :)

Answer 2

Option D, Standard deviation

Step-by-step 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

`SD = \frac{\sqrt{(X -M)^_(2) } }{N-1} \\\\SE = (SD)/(√(N) )`

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.
