The answer depends on what the graph is of: the distribution function or the cumulative distribution function.
A bimodal graph in which the modes are at the extrema.
You cannot because the median of a distribution is not related to its standard deviation.
You can't determine velocity from that graph, because the graph tells you nothing about the direction of the motion. But you can determine the speed. The speed at any moment is the slope of a line that's tangent to the graph at that moment.
A graph is represents a function if for every value x, there is at most one value of y = f(x).
You can determine the median test by arranging the data set in some order, ascending or descending, and picking out the middle data item.
A bimodal graph in which the modes are at the extrema.
To determine the wavelength from a graph, you can measure the distance between two consecutive peaks or troughs on the graph. This distance represents one full wavelength.
To determine the initial value on a graph, look for the point where the graph intersects the y-axis. This point represents the initial value or starting point of the graph.
To determine the phase constant from a graph, identify the horizontal shift of the graph compared to the original function. The phase constant is the amount the graph is shifted horizontally.
A normal distribution is symmetrical; the mean, median and mode are all the same, on the line of symmetry (middle) of the graph.
To determine velocity from an acceleration-time graph, you can find the area under the curve of the graph. This area represents the change in velocity over time. By calculating this area, you can determine the velocity at any given point on the graph.
The median is the 50% percentile.
You cannot because the median of a distribution is not related to its standard deviation.

To determine the natural frequency from a graph, identify the peak point on the graph which represents the highest amplitude or resonance. The frequency corresponding to this peak point is the natural frequency of the system.
To determine opportunity cost from a graph, you can look at the slope of the graph. The opportunity cost is represented by the ratio of the units of one good that must be given up to produce more units of another good. The steeper the slope of the graph, the higher the opportunity cost.
Unimodal is having a normal disturbution. The mean, median, and mode are all a the center. When looking at a graph, there is one maximum.
