Day 12 of the @hertechtrail @HTTDataChallenge task is to calculate total sales and average order value by region using SUM(), AVG(), COUNT() and chained JOINs across 4 tables. N/B I used ROUND() on your AVG() to reduce my decimal places. #SQLAggregation #DataAnalytics

Day 12 of 15-day Data challenge Today, I wrote an SQL query to calculate the Total sales and Average order value for each region. Grouping and aggregation are powerful tools for gaining insights from data. #HerTechTrailAcademy #HTTDataChallenge #SQLAggregation #DataAnalytics

Day 12 of my 15-Day #HTTDataChallenge Today, I dived into grouping and aggregation. My task was to write an SQL query to calculate the total sales and average order value by region. ✨Below is a snippet of my query and the results.👇 #SQLAggregation @hertechtrail @phaibooboo

8/12 4. Forgetting to group after aggregating Using aggregate functions without GROUP BY (or with incomplete grouping) is a common mistake. This omission can lead to incorrect results or SQL errors. Always review your grouping logic. #SQLAggregation #DataAnalysis #SQL

27/ You can combine COUNT with WHERE: This counts how many mystery books you have. It's like asking, "How many whodunnits do we have?" #SQLAggregation

To successfully calculate the above questions, I will have to aggregate 3 tables(Sales_reps table, account tables and order table) Below is my query and answer gotten #Hertechtrail academy #HTTDataChallenge #SQLAggregation #DataAnalytics

Exciting, isn't it? Feel free to share your thoughts! @hertechtrail @ImaNjokko @phaibooboo @fresh_gb @vicSomadina @AtiJoshua @OMOTOSHOOLAMI15 @tech_bella @atakpeku #SQLAggregation #DataAnalytics #DataSkills #HTTACohort8 #15dayscontentchallenge

Day 15💃 The North Eastern region exceeded other regions with a highest total sale of $7,744,405.36 and the largest paper quantity sold, which summed up to 1,230,378 while the Mid Western region had the lowest total sales and sales quantity sold #20dayswithdata #SQLAggregation

Day 15 #20dayswithdata Joined multiple tables (Accounts, Salesrep, Orders, Region) to retrieve total orders and average order value by region. Results show that Northeast and Southeast region were highest grossing. #SQLAggregation #DataAnalytics #MySQL

Day 15 #20dayswithdata The northeastern region recorded the highest sales and generated the highest revenue, while midwestern region recorded the lowest sales and generated the lowest revenue. #SQLAggregation #DataAnalytics

Day 15: Grouping and Aggregation Total sales for each region was calculated,North East had the highest number of sales. Average order value for each region was also calculated. #SQLAggregation #Dataintegration #20dayswithdata #hertechtrailacademy

Day 15 - Grouping and Aggregation I wrote an SQL query to calculate total sales and average order value by region. The Northeast region had the total sales while the West region had the highest average order value. #20dayswithdata #SQLAggregation #DataAnalytics
