You cannot because the median of a distribution is not related to its standard deviation.
A bimodal graph in which the modes are at the extrema.
A Box and Whisker Plot.
The median can be found out by drawing a perpendicular to the x-axis from the intersection point of both the ogives
The answer depends on what the graph is of: the distribution function or the cumulative distribution function.

you cross the bars out from order from left to right.
A bimodal graph in which the modes are at the extrema.
A Box and Whisker Plot.
A normal distribution is symmetrical; the mean, median and mode are all the same, on the line of symmetry (middle) of the graph.
The median can be found out by drawing a perpendicular to the x-axis from the intersection point of both the ogives
The answer depends on what the graph is of: the distribution function or the cumulative distribution function.
On the cumulative frequecy diagram, find 50% on the frequency [usually, vertical] axis. Draw a line to the graph and then drop a perpendicular to the other [horizontal] axis. Where it hits the second axis is the median value.
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.
You find the median to find the middle number
