Question

question 4 for a variable, if its mean = median = mode, what distribution this variable follows? normal distribution positively skewed distribution negatively skewed distribution bimodal distribution

Explanation:

In a normal distribution, the data is symmetrically distributed around the mean. This symmetry causes the mean, median, and mode to coincide at the center of the distribution. In a positively - skewed distribution, the mean is pulled to the right of the median and mode. In a negatively - skewed distribution, the mean is pulled to the left of the median and mode. A bimodal distribution has two modes, so it cannot have mean = median = mode.

Answer:

Normal distribution
