snowfall in january
inches
complete the sentences.
the distribution of snowfall amounts is best described as
. so,
the
is a more appropriate measure of
symmetric
not symmetric
Step1: Analyze the dot plot symmetry
A symmetric distribution has data evenly distributed around a center. Here, the dot plot has more dots on the left (lower snowfall) and tapers right, so it's not symmetric.
Step2: Determine measure for skewed data
For a non - symmetric (skewed) distribution, the median is a better measure of center than the mean, as the mean is affected by extreme values.
