This distribution is probably skewed to the right because the mean is larger than the median, and the lowest possible value is less than 1 standard deviation below the mean.

This distribution is probably skewed to the left because the mean is larger than the median, and the lowest possible value is less than 1 standard deviation below the mean.

This distribution is probably bell-shaped because the number of responses is large and the distributions of large data sets always have a bell shape.
