Use the frequency histogram

d. describe any patterns with the data..

Histogram displaying employee salaries in thousands of dollars, showing frequency distribution across various salary ranges.

Accepted Answer

Hi everyone, let's take a look at this practice problem. This problem says the following histogram shows the heights and centimeters of a group of employees. Use the histogram to describe any patterns or trends observed in the data. And blue texts were given our histogram for the height of employees, where the height in centimeters is along the x-axis and the frequency is along the Y axis. And we have 6 different ranges of heights. For our categories for a histogram. So the first range is going to be 34.5 to 44.5, and has a frequency of 100. The next range is 44.5 to 54.5 and has a frequency of 250. The next range is 54.5 to 64.5, and it has a frequency of 300. The next range is 64.5 to 74.5, and it also has a frequency of 300. The next range is 74.5 to 84.5, and it has a frequency of 150, and the final range is 84.5 to 94.5, and it has a frequency of 50. We're also give them 4 possible choices as their answers. For choice A, the histogram shows a bimodal distribution with two separate peaks at opposite ends. For choice B, the histogram displays a uniform distribution with frequencies roughly the same for all classes. For choice C, the histogram shows a right skew distribution, with most data concentrated on the lower end, and for choice D, the histogram shows a symmetric bell-shaped distribution with most data near the center. Now, if we look at our histogram, we see that the largest frequencies occur near the center of our histogram. So, this occurs with a frequency of 300 for the two ranges of 54.5 to 64.5 and 64.5 to 74.5, and those are actually located in the center of our histogram. The distribution is also symmetric, suggesting that there are approximately equal number of employees on either side of the peak, and the frequency actually decreases as the height moves away from the center, indicating fewer extremely short or tall employees. So based on these observations, we see that the correct answer choice actually corresponds to answer choice D, which says the histogram shows asymmetric bell-shaped distribution with most data near the center. So I hope that this explanation has been useful, and I'll see you in the next video.
