Meteorologists look for weather trends across US states in the same geographical region. Kentucky and Illinois share a border. T
lawyer [12517]

From 1991 to 2000, Kentucky's average annual temperatures (°F) were recorded as 57.5, 55.1, 52.2, 55.6, 55.6, 54.4, 54.5, 58.3, 57.3, and 55.7.

We will assess the measures of center.

To begin with, we will compute the mean.

Mean = (Total of all observed values) / (Number of observations)

Mean = \frac{57.5+55.1+52.2+55.6+55.6+54.4+54.5+58.3+57.3+55.7}{10}

= \frac{556.2}{10}

= 55.62

Next, we will determine the mode.

Mode signifies the number that appears most frequently within a set.

Considering the data set 57.5, 55.1, 52.2, 55.6, 55.6, 54.4, 54.5, 58.3, 57.3, and 55.7.

Mode = 55.6

Now we will find the median.

First, we will arrange the values in ascending order.

52.2, 54.4, 54.4,55.1,55.6, 55.6, 55.7, 57.3, 57.5, 58.3

With a total of 10 values.

Median = \frac{n}{2}th value

Median = 5th value.

Since the 5th value is 55.6.

Thus, the median stands at 55.6
