## Understanding the concept of running average

Definition of running average

Running average, also known as a moving average, is a statistical calculation that shows the average value of a set of data over a certain period. It is often used to analyze trends and patterns within the data.

Difference between regular average and running average

While a regular average calculates the average value of a set of data at a specific point in time, a running average takes into account the average value over a continuous period, moving along with the data set as new values are added.

Examples of when running average is useful

• Financial Data: Running average can be used to analyze stock prices, sales figures, and other financial data to identify long-term trends.
• Weather Patterns: Meteorologists use running average to analyze temperature, precipitation, and other weather patterns over time.
• Sports Performance: Coaches and athletes can use running average to track performance metrics such as running times, scores, and other statistics.

## Setting up your data in Excel

Before you can calculate the running average in Excel, you need to set up your data in a way that makes the calculation straightforward.

A. Organizing your data in columns and rows

The first step is to ensure that your data is organized in a clear and logical manner. Each column should represent a different variable, and each row should represent a different observation.

B. Ensuring data is sorted in chronological order

It is essential that your data is sorted in chronological order, especially if you are calculating a running average over time. This will ensure that your calculations are accurate and meaningful.

C. Creating a new column for the running average calculation

To calculate the running average, you will need to create a new column in which to display the results. This column should be adjacent to the data that you want to average, so that it is easy to reference in your formula.

## Excel Tutorial: How to calculate running average in excel

Calculating a running average in Excel can be a useful tool for analyzing trends and smoothing out fluctuations in data. In this tutorial, we will explore how to use Excel functions to calculate a running average.

### Introduction to the AVERAGE function

The AVERAGE function in Excel allows you to calculate the average of a set of numbers. It takes a range of cells as its argument and returns the average value of those cells.

### Applying the AVERAGE function to calculate running average

To calculate a running average in Excel, you can use the AVERAGE function in combination with relative cell references. By using a moving range of cells, you can calculate the average of a specific number of preceding values to create a running average.

• Step 1: Select the cell where you want to display the running average.
• Step 2: Enter the formula =AVERAGE(\$A\$2:A2) in the selected cell, where A2 is the starting cell of your data range.
• Step 3: Drag the fill handle down to apply the formula to the entire range of data.

### Using the OFFSET function for dynamic range in running average calculation

The OFFSET function in Excel returns a reference to a range that is a specified number of rows and columns from a starting cell or range. This function can be helpful in creating a dynamic range for calculating a running average.

• Step 1: Select the cell where you want to display the running average.
• Step 2: Enter the formula =AVERAGE(OFFSET(\$A\$2,0,0,ROW()-1,1)) in the selected cell, where A2 is the starting cell of your data range.
• Step 3: Drag the fill handle down to apply the formula to the entire range of data.

## Interpreting the running average results

When using running average in Excel, it is important to interpret the results to make informed decisions and predictions based on the data trends. Here are some key points to keep in mind when interpreting the running average results:

A. Understanding the significance of the running average trend
• Trend Analysis: Running average helps in analyzing the overall trend of the data over a period of time. It smooths out fluctuations and highlights the direction in which the data is moving.
• Comparative Analysis: By comparing the running average with the actual data, one can understand the consistency of the trend and identify any shifts in the pattern.

B. Identifying patterns and anomalies in the data
• Spotting Anomalies: Running average can help in identifying outliers or irregularities in the data that may not be apparent when looking at individual data points.
• Identifying Patterns: By observing the running average trend, one can identify recurring patterns or cycles in the data which can be useful for forecasting and decision-making.

C. Using running average for forecasting and decision-making
• Forecasting: Running average can be used to make predictions about future trends based on the historical data, providing insights for planning and strategizing.
• Decision-making: Understanding the running average trend can help in making informed decisions related to resource allocation, inventory management, sales projections, and other business operations.
