Discover how Python dictionaries store data as key-value pairs, differentiate them from sets, and use methods like keys, values, and items to access, modify, and extend dictionaries.
Identify and correct inconsistent data types in a data frame by verifying numeric columns, detecting non-numeric values, and converting costs to float with Python and pandas.
Master data manipulation by sorting a dataset by a numeric value in ascending or descending order using Python and pandas, with ChatGPT generated code to reveal lowest and highest values.
Explore exploratory data analysis to inspect a sales data set from a superstore, derive customer insights, profitability metrics, and market targets to guide future predictions.
Apply the group by method to mix categorical and numeric data, identifying top product categories by median order value and median cost, and explore profitability and refunds insights.
Explore confidence level, significance level, and p-value to guide hypothesis testing decisions, including interpreting intervals, choosing thresholds, and deciding to reject or fail to reject the null.
Learn to check if numeric variables follow a normal distribution using seaborn kde plots and apply transformations to non-normal data from order value, costs of goods sold, and refund.
Apply the Box-cox transformation to order_value, cost, and refund in Python using scipy.stats.boxcox. The lesson compares it with sqrt and log transforms and previews the Johnson method next.
Learn to perform a Pearson correlation test in Python to assess statistically significant relationships between order value, cost, and refund, including computing correlation coefficients and p-values.
