For example:
Convert Outdoor Activity into Minutes

 30 min = 30

 1 hr = 60
 45 min = 45

 1.5 hr = 90
 1 hr = 60

Convert Gadget Type into Numbers

 Mobile = 1
 Tablet = 2

 Laptop = 3
Convert Screen Time Level into Numbers

 High = 1
 Low = 0

After correction:

Student Gadget Screen Sleep Outdoor Academic Screen
Type Time Hours Activity Score Time Level

Student 1 1 5 6 30 65 1

Student 2 3 2 9 60 80 0

Student 3 2 4 7 45 70 1

Student 4 3 1.5 8 90 85 0

Student 5 1 4 6 60 75 1

3. Data labelling: Data labelling involves assigning meaningful categories or tags to the data.
These labels help the AI model learn patterns and make predictions.

For examples:

 Spam / Not Spam  Pass / Fail
 Good / Poor  Yes / No

ethical minds

An AI model trained on limited data may give inaccurate or unreliable results in real-world situations.
Using diverse and sufficient data helps improve accuracy and fairness.
