The number of four-period centered moving averages of a time series with 20 time periods is: a 28 b 24 c 20 d 16
Homework Answers
Answer D) 16
Explanation - Series of averages which are calculated through sequential segments of data points for a particular series of values are known as Moving averages. The moving averages possess a length, that defines the number of data points to be included for every average. In this scenario the four period centered moving averages number for a time series having 20 time periods will be sixteen.
