Solution

The SQL function that the data analyst can use to convert the text strings to floats is CAST. Here is a step by step guide on how to use it:

  1. Identify the column that contains the text strings. Let's assume the column is called 'product_price'.

  2. Use the CAST function to convert the text strings to floats. The general syntax for the CAST function is: CAST(column AS data_type). In this case, you want to convert 'product_price' to float, so you would use: CAST(product_price AS FLOAT).

  3. Include the CAST function in your SQL query. For example, if you want to select all product prices and convert them to floats, your query would look like this: SELECT CAST(product_price AS FLOAT) FROM table_name.

Remember to replace 'table_name' with the actual name of your table.
