This case study focuses on analyzing a medical dataset using Excel to uncover how health-related factors influence medical charges. The dataset contains 1,339 records and 7 columns representing key attributes. In this analysis, we explore the relationships between variables such as age, BMI, smoking habits, and medical costs, leveraging Excel tools and functions for detailed insights.
Dataset Description:
The dataset includes the following columns:
Age: Age of the primary beneficiary.
Sex: Gender of the insurance policyholder Female or Male.
BMI: Body Mass Index, which is an objective measure of body weight relative to height . Ideal BMI values range from 18.5 to 24.9.
