Question

Sometimes, a data set has two values that have the highest and equal frequencies. In this case, the distribution of the data can best be described as __________. A. Symmetric B. Negatively skewed C. Positively skewed D. Bimodal (having two modes)

Answer 1

Answer: Bimodal (having two modes)

Explanation:

Mode is a measure of central tendency, it is the number/value with the highest frequency. Bimodal as the name implies is a data set that consists of two modes that is a data set has two values that have the highest and equal frequencies. This can occur in exam scores where so many students performed well and got high marks.

Answer 2

Option D is correct.

Bimodal (Having two modes)

Explanation:

- Symmetric distribution is a situation in which the values of variables occur at regular frequencies, and the mean, median and mode occur at the same point.

- In a negatively skewed distribution, the mean is usually less than the median because the few low scores tend to shift the mean to the left.

- In a positively skewed distribution, the mode is always less than the mean and median.

- A bimodal distribution is a continuous probability distribution with two different modes, that is, two different values with the highest and equal frequencies.
