Okay, so conducting a statistical study to determine whether eating before bed influences sleep patterns involves seven steps.
00:09
The first step would be to define the research question and hypothesis.
00:14
Okay, so our research question here is does eating before bed influence sleep patterns? we have our hypothesis that eating before bed negatively affects sleep patterns.
00:24
Specifically, the hypothesis could be stated as consuming food close to bedtime leads to disrupted or poor sleep quality compared to not eating before bed.
00:34
Then we want to identify our variables.
00:37
We have our independent variable, eating before bed, yes or no, and our dependent variable would be the sleep patterns, so the quality, duration, disruptions, etc.
00:47
And then we want to determine the data type.
00:50
So here, the data required for this study would be quantitative.
00:55
So the independent variable would be categorical, yes or no, while the dependent variable is likely to be measured on a continuous scale, for example, the sleep quality rating, hours and hours of sleep.
01:07
And then for the fourth step, we would choose the method of data collection.
01:11
So to gather information, a survey or questionnaire would be suitable here to collect data on eating habits before bedtime and sleep patterns.
01:21
And then the fifth step would be to select the sampling method.
01:27
So random sampling here would probably be preferred method to ensure the results are generalizable to the larger population...
