The shape of the distribution of the weights of russet potatoes tends to be symmetrical because the
mean = median
Shape of distribution is determined by the number of peaks a distribution has, the presence of symmetry and its ability to be uniform or skewed.
We have various types of shape of distribution
a. Left skewed shape of distribution
b. Right skewed shape of distribution.
c. Symmetrical shape of distribution
d. Bimodal or Uniform shape of distribution.
Symmetrical shape of distribution occurs when the mean and the median of the distribution occur at the same point or area, hence they are same or equal to one another.
Therefore, the shape of the distribution of the weights of russet potatoes tends to be symmetrical because the Mean is equal to the Median because they occur at the same point.
Mean ≈ Median
