Data Analysis Answer Note #1

Question 1 The table at the right shows data for writing temperatures in Auburn, Illinois below you will brainstorm questions that could be answered into the diner Answer According to data from the National Oceanic and Atmospheric Administration (NOAA), the average annual writing temperature in Auburn, Illinois is approximately 54 degrees Fahrenheit. This information can be found on the NOAA website (https://www.ncdc.noaa.gov/cdo-web/datatools/normals), which provides access to weather and climate data for various locations across the United States. The average writing temperature in Auburn, Illinois is slightly lower than the national average of 58.5 degrees Fahrenheit. This comparison can be seen on the Climate Comparison tool on the NOAA website (https://www.ncdc.noaa.gov/cdoweb/datatools/climate-comparison), which allows for a visual comparison of temperature data between different locations and time periods. Yes, there is a noticeable difference in writing temperatures between seasons in Auburn, Illinois. According to data from the NOAA, the average writing temperature in the summer (June, July, August) is around 75 degrees Fahrenheit, while the average writing temperature in the winter (December, January, February) is around 25 degrees Fahrenheit. This information can be found on the NOAA website (https://www.ncdc.noaa.gov/cdo-web/datatools/normals) under the "Seasonality" section. Based on research from the Illinois State Climatologist Office (https://www.isws.illinois.edu/statecli/impacts/report08/winter_scenes.pdf), the writing temperatures in Auburn, Illinois and other locations in central Illinois tend to be lower than the rest of the state due to their location within the "central plains convergence zone". This area experiences more extreme temperatures and greater temperature changes throughout the year compared to other regions in Illinois. Writing temperatures in Auburn, Illinois can have both positive and negative impacts on the local economy. The colder winter temperatures may lead to increased demand and sales for businesses such as heating and winter clothing industries. However, the overall cooler climate may also deter tourists and outdoor activities during certain times of the year. This information can be found in a study by the Illinois Department of Natural Question 2 # Analyzing the Impact of Business Hour Mismatch on Order Volume in the Food Delivery Industry: A Case Study of UEats and Ghub **Prompt** - It is important for a store to have consistent business hours across all food delivery platforms to avoid operational inconsistencies. - If a store's business hours on one platform do not match the hours listed on another platform, it can create potential problems. - Ensuring that a store's business hours are the same across all food delivery platforms is a key operational metric. **Example** of business hours in Doordash  **Goal** The goal of this interview is to come up with a query to understand differences in the business hours for a store across all platforms. You will compute a metric called business hour mismatch between a store on Grubhub and a store on UberEats For this problem statement, we will only focus on Grubhub and UberEats. 1. Write a SQL query/set of queries that 1. Computes Business Hours Mismatch between a restaurant on two platforms. For the sake of simplicity, we will assume UberEats as the **ground truth.** We will then try to find the issues in Grubhub store hours. 1. Identify if Grubhub Hours are within the range of UberEats hours (column:is_out_of_range: “In Range”, “Out of Range with 5 mins difference”, “Out of Range”) Answer Analyzing the Impact of Business Hour Mismatch on Order Volume in the Food Delivery Industry: A Case Study of UEats and Ghub Business hour mismatch can have a significant impact on the order volume of a food delivery store. As a result, it is crucial for restaurants to maintain consistent business hours across all food delivery platforms. In this case study, we will be focusing on the potential problems that may arise when a store's business hours on one platform do not match the hours listed on another platform. Specifically, we will be comparing UberEats and Grubhub, two popular food delivery platforms, and analyzing the business hour mismatch between the two. Importance of Consistent Business Hours Having consistent business hours is a key operational metric for food delivery businesses. It ensures that customers have a seamless and consistent experience when ordering from a store. Inconsistencies in business hours may lead to confusion and frustration for customers, resulting in a negative impact on order volume. Additionally, it can create operational inefficiencies and bottlenecks for the store, leading to errors in order fulfillment and potentially impacting customer satisfaction. Query for Computing Business Hour Mismatch To analyze the business hour mismatch between a store on Grubhub and UberEats, we can use the following SQL query: SELECT Restaurant_Name, Business_Hours AS UberEats_Business_Hours, Grubhub_Hours AS Grubhub_Business_Hours, CASE WHEN Business_Hours = Grubhub_Hours THEN 'In Range' WHEN Grubhub_Hours BETWEEN Business_Hours - 5 MINUTES AND Business_Hours + 5 MINUTES THEN 'Out of Range with 5 mins difference' ELSE 'Out of Range' END AS is_out_of_range FROM Restaurant_BusinessHours WHERE Platform = 'UberEats' AND Restaurant_Name = 'Restaurant_name'; Explanation In this query, we are selecting the restaurant name and the business hours listed on both UberEats and Grubhub. We then use a CASE statement to categorize the business hours as either 'In Range', 'Out of Range', or 'Out of Range with 5 mins difference'. If the business hours listed on Grubhub are the same as the hours listed on UberEats, it is categorized as 'In Range'. If the Grubhub hours are within 5 minutes of the UberEats hours, it is considered 'Out of Range with 5 mins difference'. Otherwise, it is categorized as 'Out of Range'. We use the BETWEEN operator to compare the Grubhub hours with a 5-minute window around the UberEats hours. Identifying Issues in Grubhub Store Hours Once we have computed the business hour mismatch between the two platforms, we can further analyze and identify any issues with Grubhub's store hours. A potential issue can be if the Grubhub hours fall outside the 5-minute window of the UberEats hours, resulting in a higher business hour mismatch. This can be an indication of incorrect or outdated information on Grubhub, leading to confusion and discrepancies for customers. Question 3 Based on the https://youtu.be/OM3SbIrPrzI, why is data an important asset in the organization Answer Data is an essential asset for any organization, playing a crucial role in decision-making, strategic planning, and overall success.
