The video tutorial covers the measures of central tendency: mean, median, mode, and range. It begins with a brief review of these concepts and then provides several examples to demonstrate how to calculate each measure. The tutorial includes step-by-step instructions for ordering numbers, finding the range, identifying the mode, calculating the median, and determining the mean. Additionally, a word problem involving candle sales is solved to illustrate the application of these concepts in a real-world context. The video concludes with a preview of the next topic, standard deviation.

What does the 'mean' in statistics refer to?

• The difference between the highest and lowest values

• The average value of a data set

• The most frequently occurring value

• The middle value of a data set
