As a Data Analyst, your job is to gather, clean, and study data sets to help solve problems.

In this thread, I will solve the most common question you would be asked to solve.

Let's get started

Here is a quick snapshot of the data set we going to use

(From March to December)
1. How many Pens are Sold?

The total of a specific number of items sold.

Formula used: Formula =SUMIFS(dataset[Sold],dataset[[Item ]],L5)

By using this method it is not limited to only one item (Pen),

If you write the item name in the cell (L5) you can get other items sold values too.

2. How many Items were returned in Oct-21?

This will show you the total number of items returned in Oct-21.

Also, if you change the Month in L5 Cell, you can get the total number of returned items in that Month.

Formula used: =SUMIFS(dataset[Rreturned],dataset[Month],L5)

3. Total Sold in a Given Period.

This will show you how many items were sold in a given period of time.

Also, if you change the End or Start Date, values will change accordingly.

Formula used: =SUMIFS(dataset[Sold],dataset[Month],">="&L5,dataset[Month],"<="&L6)

4. How often did 1 item sell more than 500 times each month?

This will catch the number of times one item has sold more than 500 times.

Formula used: =COUNTIFS(dataset[Sold],">500")

5. What is the Average of Item Returned?

This will show you the average of each item returned.

If you change the item name on Cell L5, you will get the average of that item returned.

Formular used: =AVERAGEIFS(dataset[Rreturned],dataset[[Item ]],L5)
