A teаm оf envirоnmentаl scientists hаs cоllected air-quality measurements from hundreds of monitoring stations across the country. The dataset includes the following information: Station ID City Temperature Humidity Air Quality Index (AQI) Measurement Date After receiving the dataset, the researchers discover several issues: Some temperature values are missing. City names are not consistently capitalized. Several monitoring stations appear more than once. Some temperatures were accidentally stored as text instead of numbers. A few AQI values appear unusually high compared to the rest of the dataset. Answer the following: a. Identify at least four data quality issues that should be addressed before performing any statistical analysis. b. Explain why Exploratory Data Analysis (EDA) should be performed before building a machine learning model. c. Which Python concepts or techniques learned in this course could help correct each of these problems? d. Explain why failing to clean the dataset could negatively affect the results of a machine learning model.
