Final answer:
The best measure of central tendency with interval/ratio (NOT skewed) data is the mean.
Step-by-step explanation:
The best measure of central tendency with interval/ratio (NOT skewed) data is the mean.
The mean, also known as the average, is calculated by summing up all the values in the data set and dividing it by the total number of values.
For example, if you have the data set 10, 20, 30, 40, the mean would be (10 + 20 + 30 + 40) / 4 = 25.
