20. The world is competitive nowadays. People face competition in even the tiniest tasks and are
expected to give their best at every point in time. When people are unable to meet these
expectations, they get stressed and could even go into depression. We get to hear a lot of cases
where people are depressed due to reasons like peer pressure, studies, family issues,
relationships, etc. and they eventually get into something that is bad for them as well as for
others. So, to overcome this, Cognitive Behavioural Therapy (CBT) is considered to be one of
the best methods to address stress as it is easy to implement on people and also gives good
results. This therapy includes understanding the behaviour and mindset of a person in their
normal life. With the help of CBT, therapists help people overcome their stress and live a happy
life.
For the situation given above,
1. Write the problem statement template
2. List any two sources from which data can be collected.
3. How do we explore the data?

21. Take a look at the confusion matrix:

The Confusion Reality

Yes No
Matrix
Yes True False
Positiv Positiv
Prediction
e e
(TP) (FP)
No False True
Negativ Negativ
e (FN) e (TN)
How do you calculate F1 score?
