Figure 4. The Colonel tracks water consumption for each chicken in his flock.
The Colonel measured daily water consumption for 30 chickens in his flock. Use the
frequency
distribution below to answer the following questions.
Figure 5. Frequency distribution of daily water consumption across 30 chickens.
Each bar indicates how many chickens consumed water within that range.
Question 1: Number of peaks
Which statement best describes the number of peaks in the frequency
distribution?
Question 2: Shape
Which statement better describes the shape of the frequency distribution?
Complete solution
Question 1: Number of peaks
Answer: The distribution has a single peak.
Looking at the distribution, there is one clear high region at the 200-225 mL range where
the bar is tallest (10 chickens).
The bars on either side are shorter, creating a single peak pattern (unimodal distribution).
Question 2: Shape
Answer: The distribution has an asymmetrical shape.
If you imagine a vertical line through the peak (200-225 mL), the two sides do not perfectly
mirror each other.
The right side extends slightly further (with bars at 250-275 and 275-300) compared to the
left side, making this distribution slightly asymmetrical (right-skewed).
