Introduction

In this article, we will be reviewing the capabilities of ChatGPT as a data analyst. The project at HAND is an e-commerce customer purchasing analysis. We will go through a series of queries and compare our own analysis with that of ChatGPT. By doing so, we aim to evaluate ChatGPT's performance and determine whether it can potentially replace human analysts in certain tasks. So let's dive in and see what insights we can uncover!

Scrolling Through the Data

The first step in our analysis is to scroll through the data and ensure that everything is in order. We need to check the columns and the information available to us. After downloading and browsing through the data, we can proceed to the next step.

Uploading and Renaming the Table

Once we have familiarized ourselves with the data, we need to upload it and establish a connection. We will Create a new schema called "sales" and create a new table within that schema. After uploading the table, we will rename it to "customers" for Clarity. This will allow us to easily reference and analyze the data moving forward.

Analyzing Top Customer Segments

The first question we need to answer is: What are the top five customer segments Based on total spend? This information is crucial for targeting marketing and optimizing for high-value customers. We will alter the table by selecting the membership type, summing the total spend, and rounding it for a neater presentation. By grouping the data by membership type and ordering it by total spend in descending order, we can identify the top five customer segments.

Identifying Recent Purchases

Next, we need to determine how many customers have made a purchase in the last month. This allows us to gauge the recent activity of our customer base. We will alter the table by selecting the account and giving it the name "last purchases". By using the "WHERE" clause to filter the data for purchases made in the last 30 days, we can count the number of customers and present this information.

Average Age of Customers in Each City

Understanding the demographics of our customer base is crucial for effective marketing strategies. We need to calculate the average age of customers in each city. By selecting the city column and applying the average age function, we can group the data by city and order it by average age. This will provide us with insights into the age distribution among our customers in different cities.

Cities with the Lowest Spending

To identify cities with the lowest spending, we need to analyze the total spend within the past three months. By selecting the city column, rounding the total spend, and grouping the data by city, we can order it by total spend. This will allow us to identify the cities that have the lowest spending, enabling us to focus on these areas for improved sales and marketing efforts.

Total Profit for Each Membership Type

Analyzing the total profit for each membership type helps us understand the financial performance of different segments. To calculate this, we will add a new column called "total cost" and update the table accordingly. By multiplying a random number with the total spend, we can generate the total cost. Then, by subtracting the total cost from the total spend and rounding the result, we can calculate the total profit for each membership type.

Top Three Customers with Highest Satisfaction Level

Customer satisfaction is a key metric for any business. We need to identify the top three customers with the highest average satisfaction level. By selecting the customer's ID, calculating the average rating, rounding it, and ordering it by average rating, we can determine the top three customers who are most satisfied with our products or services.

Average Number of Days Between Purchase for Each Gender

Understanding the purchasing behavior of different genders can inform marketing strategies. We will calculate the average number of days between purchases for each gender. By selecting the gender column, taking the difference in days between the last purchase, and rounding the result, we can analyze the average number of days between purchases for each gender.

Conclusion

After analyzing the performance of ChatGPT as a data analyst, we can draw some conclusions. While ChatGPT was able to perform queries quickly, it lacked certain presentation and data manipulation capabilities. Our analysis involved altering table names, renaming columns, and formatting data for a clearer representation. Although ChatGPT has the potential to replace analysts in some tasks, there is still a need for skilled analysts who can interpret data, feed it correctly, and make improvements to ensure accurate and actionable insights. While ChatGPT may replace certain analyst roles, there will always be a need for exceptional analysts who can provide valuable insights and drive informed decision-making.
