The data science lifecycle is a systematic process that data scientists follow to extract valuable insights from raw data. It involves stages such as problem definition, data collection, cleaning, exploratory analysis, feature engineering, modeling, evaluation, deployment, monitoring, and communication of results. The lifecycle is iterative, allowing for revisiting stages based on new insights or changes. Flexibility and adaptability are crucial, as data scientists navigate through the lifecycle to drive informed decision-making.The correct option is:Run classification models to predict which product characteristics are likely to appeal to each customer.Explanation:Run Classification Models:This is the most suitable option. Given past purchases, the data scientist would likely want to build predictive models (such as classification models) to understand patterns and predict which product characteristics are likely to appeal to each customer. Classification models can be trained on historical purchase data to identify patterns and preferences.Incorrect options:1. Presentation of Results:Not the next step. The data scientist usually doesn't jump directly into presenting results without analyzing and deriving insights from the data first.2. Create Scatter Plots:While scatter plots are useful for visualizing relationships between variables, they don't necessarily address the specific task mentioned. The task is about predicting product characteristics that are likely to appeal to customers, which requires more advanced analysis than scatter plots.3. Reformat Data into a CSV File:Data formatting and cleaning are important, but this step usually comes after the initial analysis. Moreover, the task mentioned is more about deriving insights and predictions from the data, not just preparing the data for storage or analysis.The task "Run classification models to predict which product characteristics are likely to appeal to each customer" is an example of the Modeling the data step in the data science lifecycle.Conclusion:The correct option involves running classification models to predict customer preferences based on past purchases. This aligns with the goal of leveraging data science techniques to gain insights and make predictions, which is a key step in the data science lifecycle. The other options may be relevant at different stages of the process but are not the immediate next step based on the provided scenario.The task of running classification models to predict customer preferences aligns with the Modeling step in the data science lifecycle, where predictive models are developed to extract insights and make predictions based on the available data.

Assume you are giving a dataset that is based on user surveys. You notice that many surveys have missing fields. You also notice that some surveys have fields on a scale of 1 to 5 while others are on a scale of 1 to 10. The survey has mixed information using metric measurements and the imperial system. There are some different fields depending on the country, but they all relate to the location of the participant. You also notice that some values just don't make sense. What analysis would you do on the data set to come up with a data cleaning plan? What are some normalization and cleaning tasks you could do based on the information provided in this description?
