Find the Difference between Two Lists

If you've got two lists or table to compare, most of the time you can use the equal sign to compare the cell values. But sometimes there are complications like having more than one value, values (text or string values) are separated by delimiters (e.g., commas, semicolons, etc.) or the values are not in the "correct" order. Doing the simple cell to cell comparison is not applicable and that's when you can use Power Query to help compare values.

Google Sheets - Finding Duplicate Values

When you get a table or list from others or some systems, you might get duplicate records. If you wanted to find those duplicates whether it be in a one column table or a multiple column table, it's fairly easy to do within Google sheets. I'll show a couple of ways this can be done with formulas and with a Pivot Table. Also if you wanted to just delete duplicate records ( and didn't want to bother with the analysis of which records is a duplicate), closer to the end of the video I'll show the command to do this quickly.

Extract Values from Column based on Another Column

There are times when you get data from someone that's not in a spreadsheet but looks like it came from one. The file you get may be a text file, but it looks like it's almost in some table format and had some calculations. You'd want to take the data or content from the file and do further analysis, so that would involve putting it into Excel. If it was a small file, it's a simple copy and paste, but if it was a large file it would take a long time to copy/paste all that data. You can actually bring it into a spreadsheet but you'd first need to see if there were some patterns. Hopefully if someone gave you a text file that seems to have calculations in it, the file would have come from some application that did the calculation and uniformly had the output in some repeating format (like some dash marker to indicate a total row was next) then you could extract data based on a previous row. This video will show how to use values from one row to find a pattern, use some conditions to compare and extract it to make a new column to help make a proper table to support further analysis

Google Sheets - Create a Gauge or Speedometer Chart

Gauge charts aka Speedometer charts are one of those fancy looking charts that try to represent a metric with the car dashboard analogy. This dashboard analogy is good in small doses because it's preferable to have something similar to a basic car dashboard as opposed to airplane cockpit dashboard. Thankfully creating a gauge chart in Google Sheets is fairly straight forward and easy to do. So buckle up and check out the video.

Google Sheets - Create a Dynamic Dropdown List

Want to learn how to create a dynamic drop down list in Google Sheets? It happens when you click a small drop down arrow in the cell and it shows you a list of choices. Then after the first selection from that drop down list will help filter another drop down list for another set of options to choose from. This is pretty easy to do by involving the named ranges, the data validation feature and the INDIRECT function.

Perform a Two Sample Test in Excel (paired t-test)

If you're testing a scenario that looks at a before and after situation AND wanted to know if there the result is based on random chance or NOT, you probably want to use a paired t test. Excel has some neat functions that give you the ability to do a paired or dependent t test easily. This video will show a quick way using the Data Analysis feature and then the various functions and formula to do it in a more manual (but challenging) way.

Google Sheets - Covert Columns or Rows into Comma Separated Values

Been in a situation where you had to convert values in columns or rows into comma separated values (csv)? Maybe you got a column of value and you needed to query it in another system, BUT that system needed the input values separated by commas (or semicolons). Using Google sheets, there are actually a couple of ways you can do this and I'll show three examples with three different functions to make it happen.
