Research about the Number of Hours People Sleep on Regular Working Days
The following paper seeks to conduct research based on the following topic, “how many hours of sleep do most people get.” The following hypothesis will be used, during workdays most people sleep less than eight hours.
Sampling design
The data will be gathered at the place of work. I will use simple random sampling as the sampling design. This is a sampling technique where a small group known as the sample is selected from a large group of people that is known as the population. In simple random sampling, every member has an equal chance of being selected. The whole procedure of sampling is done in a single step (Bryman, 2012). That gives each subject the opportunity to be selected. The best thing about this sampling technique is the fact that it is a fair way of selecting samples from an individual population. In that, each member of that community has equal opportunities of being selected. It is also easy to use and yields accurate results. In this context, I will select sixteen of my workmates randomly. I will sample eight females and eight males.
Data will be collected using questionnaires. A questionnaire is a simple to use research instrument that consists of a series of questions as well as other prompts that are used to retrieve information from respondents (Stevens et al, 2014). Even if it is hard to tell whether the respondent is telling the truth, questionnaires are practical. They can be used to gather crucial information from the respondents. Another good thing about questionnaires is the fact that information can be collected from a large population within a short period. Questionnaires are also cheap to use. Information from questionnaires is easy to quantify. The questionnaire I will use will consist of one question that is, on an average basis, how many hours per night do you sleep during regular working days (Levy & Lemeshow, 2013).
The following is data retrieved from the sixteen people 8 males and 8 females who were sampled.

No Gender Average sleeping time (hours)
1 Male 6
2 Male 8
3 Female 8
4 Male 6
5 Female 7
6 Female 8
7 Female 6
8 Female 5
9 Male 6
10 Male 7
11 Male 5
12 Male 8
13 Female 8
14 Female 8
15 Male 7
16 Female 7

To calculate the mean, all the sleeping hours will be added and then divided by the number of people sampled.
Total sleeping hours are 110 hours
Total number of people is 16
To find mean, 110 divided by 16
The Mean is 6.875 hours
The mode is the most frequent number in particular data. From the above data, 8 is the most frequent number.
To find the median, the number of hours will be sorted from the lowest to the highest. After sorting, the number in the middle will be the median.
5, 5, 6, 6, 6, 6, 7, (7, 7)7, 8, 8, 8, 8, 8, 8
Since the data has an even number of data to find the median, the two average middle numbers will be averaged. Add 7 and 7 then divide by 2. 14 divided by 2 is 7. Therefore, the median is 7.
Comparative Analysis
The mean or the median are useful indicators of the central tendency. From the data, the majority of people get less than 8 hours sleep during regular working days. 62.5 % of people sampled, reported to getting less than 8 hours sleep. In conclusion, most people of the people tested, tend to sleep 7 hours per night.
