A Level Maths Notes: S2 – Mode of a Continuous Distribution
The mode of a continuous distribution is the most probable value
of the random variable associated with the distribution. If we sketch
the probability distribution function against
it
will typically have a maximum. Finding the mode then becomes a matter
of finding the turning point, or solving the equation![]()
Example: Find the mean of the probability given by![]()
![]()
The Uniform distribution does not have a mode since
everywhere,
except at the ends. Also if
is
increasing then the mode is at the upper end of the range of
and
if
is
decreasing then the mode is at the lower range of the distribution
