Understanding Moving Averages

The video tutorial introduces the concept of moving averages, explaining their use in science and stock market predictions. It focuses on simple moving averages, particularly a three-year moving average, and provides a step-by-step guide on calculating it. The tutorial also demonstrates how to plot these averages on a graph, highlighting their practical applications in investment strategies. The moving average is described as a subset of data that shifts as new data is collected, offering insights into trends over time.

What is a moving average primarily used for?

• Measuring economic growth

• Predicting weather patterns

• Predicting stock movements

• Calculating interest rates

In a simple moving average, what is the first step in the calculation process?

• Calculate the median

• Identify the subset to average

• Determine the total data set

• Plot the data on a graph

For a three-year moving average, which years are included in the subset for year 3?

• Years 3, 4, and 5

• Years 2, 3, and 4

• Years 4, 5, and 6

• Years 1, 2, and 3
