Do companies ever release these sort of datasets?

Dataset

You can use Kaggle, or you can also try to create your own dataset. from the companies, they might have proxy to let their data taken however they also have to protect their business and privacy of their customer so it might not be easily available. Some of them provide this though, such as youtube data api https://developers.google.com/youtube/v3

Does a market researcher need to be skilled in using these data analysis skills?

what does lambda mean in this context

rfm = df_data2.groupby('Customer ID').agg({'InvoiceDate': lambda date: (today_date - date.max()).days,

'Invoice': lambda num: num.nunique(),

'TotalPrice': lambda TotalPrice: TotalPrice.sum()})

why is it necessary to apply a log transformation to rfm?

I think there is some code missing in data cleaning?

The comment says something different than what the code does:

# drop the records who have been cancelled -> Invoice start with C

index_name = df_data[(df_data['Quantity']<0)].index

df_data.drop(index_name, inplace = True)

I'm looking at doing brief no. 2, would you mind just verbally reiterating the expectation/ example of that?

I imagine it may involve more writing about the bias is all.
