Measures of Center in Statistics

The video tutorial explains the three measures of center: mean, median, and mode. It demonstrates how to calculate each measure using a data set, with a focus on identifying which measure equals 45. The mean is calculated by summing the data and dividing by the number of data points, resulting in 45. The median is found by ordering the data and averaging the middle values, resulting in 47. The mode is the most frequently occurring number, which is 32. Liam's measure of center, 45, corresponds to the mean.
