Formatting Data for Collection Sheets Can be Broken Down into These Four Simple Steps, Making Analysis More Successful.

formatting data

Our client partners often struggle with formatting data collection sheets. Without a solid structure, the analysis phase becomes tedious (or even impossible).

As we help clients dig into home-grown Excel data sheets, we find they have the best intentions of collecting performance data. However, when they attempt to analyze the data, they discover that the way they are formatting data limits their ability to create actionable intelligence and visualizations.

Common issues include using any text entry that the user chooses, keeping different time periods on separate tabs, and not standardizing reason codes for downtime or scrap.

Preparing Data for Analysis in Excel, Power BI, or Tableau

Excel, Power BI, Tableau, and Minitab are powerful tools for data analysis, but before you can get started with analysis, formatting data correctly becomes a priority. Proper data formatting is crucial to ensuring that you can work with your data accurately and efficiently.

You may be asking, Where do we start?

Here are 4 simple steps to take formatting data for Excel or Power BI to the next level:

Step 1 Organize your data collection

To perform data analysis, your data collection must first be organized in a way that makes the analysis simple. We must think about how the software we use processes the data. For ease of computation, it is best to put all the data in one single table or database. Related data should be organized, with different types of data separated into columns.

It is best practice to format all data in the same table or database. Commonly, we see some managers practice storing weeks or months of data on separate Excel worksheets. This makes the analysis difficult due to having to amalgamate all the individual tables into one. In this scenario, the person who sets up the analysis will end up performing multiple moves with the data, and there will be an additional element of human error introduced. Additionally, someone will inevitably change the structure of one or more of the individual tabs, and then a simple copy and paste becomes tedious.

When we design our data table, we want to make it as simple as possible for the analysis phase.

For example, to format a table that contains machine production and downtime data, you could use a format that includes the following columns:

This format allows you to easily track production and downtime data for each machine on each shift. You can use this data to identify trends and areas for improvement, such as machines that are frequently down or areas where production can be increased. You can also use this data to calculate key performance indicators (KPIs) such as overall equipment effectiveness (OEE) and downtime percentage.

Here is an example of what the table might look like:

Step 2 Standardize data formats

Standardizing data refers to the process of using consistent formats for data types such as dates, currencies, and percentages. The goal is to make sure that the data is uniform and can be used consistently throughout your data set.

Standardizing your data is important for several reasons. First, it makes it easier to work with your data and reduces the risk of errors. Second, it can improve the accuracy of your analysis by making it easier to compare and combine data.

Here are some examples of how to standardize data:

When standardizing your data, it’s important to be consistent throughout your data set. If you use different formats for the same data type, it can lead to confusion and errors in your analysis.

Step 3 Check for data accuracy and completeness

After you ensure that you have consistency in formatting your data, you need to make sure that it is accurate and complete. This means checking for errors, missing data, and inconsistencies. If your data is inaccurate or incomplete, it will be difficult to work with and could lead to inaccurate analysis results. Inaccurate analysis results could lead to a waste of your time, or they could risk your professional image and even damage working relationships.

Here are a few ways to identify incomplete data:

If you identify incomplete data, you may need to take steps to fill in the missing data or adjust your analysis accordingly. Depending on the nature and extent of the incomplete data, this may require additional data collection, analysis, or assumptions. It’s important to be transparent about any incomplete data and how it may affect your conclusions or recommendations. Always inform the audience if there are assumptions being made to fill in gaps from incomplete data sets.

Step 4 Remove duplicates

Duplicate data can cause problems when analyzing it, so it is important to remove duplicates. Having categories or segments of the data repeat can skew the analysis significantly. You can do this manually or by using Excel’s built-in Remove Duplicates function or Power BI’s Remove Duplicates transformation.

Note that when removing duplicates, you can choose to keep the first occurrence of each duplicate value or the last occurrence. You can also use conditional formatting to highlight duplicate values instead of deleting them, allowing you to review them manually and decide whether to keep or remove them.

No matter how you perform the review and removal of duplicates, it’s important to review the data carefully after removing duplicates to ensure that the remaining data is still accurate and meaningful. In some cases, removing duplicates may have unintended consequences, such as making an error that leads to a gap in the data. Therefore, it’s important to be cautious when removing duplicates and to have a clear understanding of the data and how it will be used.

Next Steps

Once your data is cleaned and prepared, you can begin to analyze it. Microsoft Excel, Power BI, or Tableau can be used to create charts, tables, and other visualizations to help you understand patterns, trends, and relationships in the data. The goal is to identify any insights or trends that can help you make better decisions.

Remember that data cleaning and analysis are iterative processes. You may need to go back and repeat steps or perform additional cleaning and analysis as you uncover new insights and information. You may notice visual outliers in the charts and research that indicate some unusual special cause needs to be removed. However, by following the above steps, you can be confident that your data is accurate, consistent, and meaningful, and that you are able to use it to make informed decisions.
