Question

These box plots show daily low temperatures for a sample of days In two different towns

Answer 1

Answer:

Choice A is correct

Step-by-step explanation:

The distribution for town A is symmetric, but the distribution for town B is negatively skewed. From the box plots it is clear that the tails of the box plot  for town A are equal in length while for town B the left tail is longer implying a negatively skewed distribution.

Answer 2

Answer:

option c)

both distribution are symmetric.

Step-by-step explanation:

Symmetric vs skewed

In symmetric data, the median cuts the box into two equal pieces.

Just like in case of both town:

TownA

             30(median)

   20                 40

TownB

             40(median)

    35              45  

Skewed data show a lopsided box plot, where the median cuts the box into two unequal pieces. If the longer part of the box is to the right (or above) the median, the data is said to be positively skewed and if the longer part is to the left (or below) the median, the data is negatively skewed.
