IELTS Listening Part 3: A Survey on Student Sleep

Part Three. You will hear two psychology students discussing a survey they did on student sleep.

First, you have some time to look at questions twenty-one to twenty-five.

Now listen carefully and answer questions twenty-one to twenty-five.

Right, Jack, I've finally finished entering all the survey data.

Brilliant! How many responses did we get in the end?

A hundred and fifty, which is more than we hoped for.

On average, students sleep about six hours a night.

Only six? That's way less than the recommended eight!

And guess which group sleeps the least?

Um... final-year students, because of exams?

Nope! It's actually the first-years.

Really? I wonder why that is.

I think a lot of them have part-time jobs in the evenings.

I'm not convinced. I'd say it's mainly their phones.

Most of them said they check social media in bed.

Hmm, that's true, but we didn't actually measure screen time.

Ugh, you're right. That's a gap in our data.

Before you hear the rest of the conversation, you have some time to look at questions twenty-six to thirty.

Now listen and answer questions twenty-six to thirty.

Oh no. There's another problem, too.

Hardly any engineering students filled in the survey.

So our sample isn't really balanced, is it?

Also, people might not remember how long they actually slept.

Oh! What if we asked a few volunteers to keep a sleep diary?

For a week? That would make our results much more reliable!

Okay, so you'll do the graphs,

and I'll write the literature review.

Let's meet here again on Thursday at two.

Deal. As long as I'm not too tired!

That is the end of Part Three.
