-Regression is a simple, common, and highly useful data analysis technique, colloquially referred to as "fitting a trend line." Regression identifies the strength of relationship between one or more features and a single label. Its simplicity, predictable behavior, ability to forecast, and high level of interpretability means this technique is used throughout finance, business, social sciences, epidemiology, and medicine.
+Regression is a simple, common, and highly useful data-analysis technique, colloquially referred to as "fitting a trend line." Regression identifies the strength of relationship between one or more features and a single label. Its simplicity, predictable behavior, ability to forecast, and high level of interpretability means this technique is used throughout finance, business, social sciences, epidemiology, and medicine.
 
 In this module, we'll take a deeper dive into how regression works, understand its limitations, and learn how to assess its performance.
 
 ## Scenario: Veterinary Clinic Overrun
 
 Throughout this module, we’ll be using the following example scenario to explain the concepts underlying regression. This scenario is designed to provide an example for how you might use this technique when analyzing future data.
 
-The avalanche-rescue dog charity you run has had a sudden wave of illness. After a day of retraining and some social activities, many dogs you work with have fallen unwell, the main symptom being fever (elevated body temperature). Concerned for the dogs who haven't yet presented with symptoms, your team has collected basic information on the first 100 dogs who fell ill. Your job is to identify which types of dogs have higher risks of illness, so that they can be proactively checked by the vet.
