### Histogram of Arrivals

**Description:**

This histogram illustrates the frequency distribution of arrivals per minute. The horizontal axis (x-axis) represents the number of arrivals per minute, ranging from 0 to 12. The vertical axis (y-axis) indicates the frequency, specifically how many times each arrival rate occurred within the dataset.

**Details:**

- The histogram bars are color-coded in a gradient ranging from red, orange, yellow, green, blue, to purple, which helps differentiate the frequency of different arrival rates.
- The highest frequency observed is around 15 arrivals per minute, primarily concentrated between 3 and 5 arrivals per minute.
- The distribution shows a peak around 4 arrivals per minute, suggesting this is the most common rate of arrivals.
- As the arrival rate increases beyond 5, the frequency decreases, indicating fewer occurrences of higher arrival rates.
- This pattern of distribution appears to follow a somewhat normal distribution curve, with a slight skewness to the right.

This visualization is useful for understanding patterns in the data, such as identifying the most common arrival rates and observing how frequently higher and lower rates occur.

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
