which distribution is positively skewed?\n○ a.\n○ b.\n○ c.\n○ d.
which distribution is positively skewed?\n○ a.\n○ b.\n○ c.\n○ d.
Answer
Explanation:
Step1: Recall positively - skewed distribution characteristics
A positively - skewed distribution has a long tail on the right side. The majority of the data is concentrated on the left side of the distribution.
Step2: Analyze Option A
Option A is a symmetric distribution. The data is evenly spread around the center, so it is not positively - skewed.
Step3: Analyze Option B
In Option B, the majority of the data is on the left side and there is a long tail on the right side, which is characteristic of a positively - skewed distribution.
Step4: Analyze Option C
Option C is a negatively - skewed distribution. The majority of the data is on the right side and there is a long tail on the left side.
Step5: Analyze Option D
Option D is a box - and - whisker plot. The right whisker is shorter than the left whisker, indicating a negatively - skewed distribution.
Answer:
B.
