Question

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

Answer 1

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  

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

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.

Answer 2

Standard deviation, really hope this helps you out :)
