Directions for the Data Collection Activity

• Complete the activity by cutting and pasting the bolded components 1-8 below directly into your discussion board post, do not attach a document.
• Decide on a name for your study and write it in the subject line of your post.
• I have described what I expect for each component (see below) and included an example (in green,) do not use my example.
• When you include your raw data, please do so horizontally separated by commas as I have done, to avoid excessive scrolling.
• You are required to comment on the projects of at least 2 classmates. Keep your comments about the content of the activity. Comments such as, “I liked your activity…”, “You did a good job….” Will not count!
• Keep a copy of this activity for yourself because you will use the data for another activity.
• Be creative in how you collect data. You don’t have to necessarily get it from people, maybe you will go to grocery stores and collect nutritional data, or you might be able to collect it online…. have fun!

Required Activity Components

1. Description of the study: What is the purpose of your study, what are you trying to find out? Think it through and be specific. For example: My study is to try to find out the average amount of money that MXC students spend on text books including e-texts and class software by surveying 25 random MXC students.

2. Variable of interest: What is the measurement you are taking, in other words, what does each data piece represent? In the example above the variable of interest is: the amount of money each student spent on texts including e-texts and class software.

3. Population: What is the overall group you are studying? In the above example, it would be: the pertinent information from all MXC students. Keep in mind that you will need to keep your population rather narrow, it’s probably not realistic to do a study about people in the US because you would have to make sure to get information from all regions of the country.

4. Sample: What subgroup of the sample did you get the information from? In the above example, it would be- the pertinent information received from 25 random MXC students.

5. Data collection method: Explain how you collected your data and specify the method and how your data collection fir that method. For example, perhaps for the above example: I asked 5 instructors if they would administer the survey question to 5 random students in their class. This is an example of stratified sampling, each class is a strata and there was a random sample taken from each strata.

6. Measures I took to ensure a representative sample: In the above example, I might say: To ensure a representative sample I made sure to include both daytime and evening classes and various classes across the spectrum such as general education courses and health science courses.

7. Raw data: For the above example, it might look like this: Data is rounded to the nearest dollar:230, 543, 109, 476, 219, 72, 789, 111, 360, 967, 445, 301, 836, 281, 547, 682, 725, 370, 177, 265, 484, 638, 40, 279, 74

Can someone help me with this I need to create my own example of this, but I'm not what idea to use I need to answer all the questions and create a problem  

Answer 1

1.My study is trying to find out average no. of subjects studied by students in coaching institution by surveying 35 random students over 5 coaching institution over 3km radius of the place I live in.

2. The no. of subjects the students study in the coaching centres.

3.The pertinent information from all the students studying in those 5 coaching insitutions

4. The pertinent information from all the students studying in those 5 coaching insitutions

5. I first found out 10 coaching institutes around 3km radius of the area where i live in. Then I picked a random sample of 5 from those 10 coaching institutes. After that, I visited those 5 coaching institutes and from each coaching institutes, I picked a random sample of 7 students through systematic sampling of k=3 that is every 3rd student until i reach a sample of 7, who came to study in the coaching institute. This is a mixture of stratified sampling and systematic sampling where we have 5 strata as in coaching institutes and the sample under each stratum is picked by systematic sampling.

6. To ensure a representative sample i made sure to include students of both morning and evening shifts and also i have chosen a completely random sample out of my data where I have no connection to my sample whatsoever and completely unknown and random. The students were of different streams background which i have not taken into consideration to keep my sample completely unbiased.
