QuestionHere are three histograms.
(a) Which histogram is best described as bimodal?
Histogram A Histogram B
(b) Which histogram is the closest to being symmetric?
Histogram A Histogram B
(c) Which histogram Histogram C
Histogram A Histogram B Histogram C
(d) Which histogram is skewed to the left the most?
Histogram A Histogram B
Explanation
Histogram C
Studdy Solution
STEP 1
1. A bimodal histogram has two distinct peaks.
2. A symmetric histogram has a similar shape on both sides of its central peak.
3. A histogram skewed to the left has a longer tail on the left side.
STEP 2
1. Identify the bimodal histogram.
2. Identify the symmetric histogram.
3. Identify the histogram skewed to the left.
STEP 3
Examine each histogram to determine which has two distinct peaks.
- **Histogram A**: Peaks around the middle with a gradual decrease on both sides.
- **Histogram B**: Has two distinct peaks, one around 3 and another around 7.
- **Histogram C**: Peaks towards the right with a gradual increase from left to right.
Histogram B is best described as bimodal.
STEP 4
Examine each histogram to determine which is closest to being symmetric.
- **Histogram A**: Peaks around the middle with a gradual decrease on both sides.
- **Histogram B**: Has two distinct peaks.
- **Histogram C**: Peaks towards the right with a gradual increase from left to right.
Histogram A is the closest to being symmetric.
STEP 5
Examine each histogram to determine which is skewed to the left.
- **Histogram A**: Peaks around the middle.
- **Histogram B**: Has two distinct peaks.
- **Histogram C**: Peaks towards the right with a gradual increase from left to right.
Histogram C is skewed to the left the most.
Answers:
(a) Histogram B is best described as bimodal.
(b) Histogram A is the closest to being symmetric.
(c) Histogram C is skewed to the left the most.
