I don’t need it to be a full on essay, but just an outline. I need someone who knows how an executive summary and appendix should be written. I’ve uploaded the documents that the outline will be about. To do this assignment, you’ll need knowledge of statistics and know what’s significant. This project shouldn’t take long, even though it’s got a couple spreadsheets. These are just to help you decide which points are important and which is not.
1 page outline executive summary – here are the instructions:
Executive Summary
Summary of your research.
- Focus on communicating the results and interpretations of your results. You will not be able to comment on every little finding, so you will have to make some judgments about what might be the most interesting or revealing results.
- Discuss inferential statistics and how your survey data can be used to estimate or test population parameters such as the population mean and population proportion.
1 page outline reflection summary – here are the instructions:
Reflection summary
Thoughts on how my research has changed your point of view of statistics.
- How will those ideas influence or impact your personal or professional life?
1 page appendix:
- Appendix(This includes your supporting data):Introduction.Data Collection Plan.Descriptive Results.Inferential Statistics.Table of data from the Survey Data Generator.

| 4) The sample size is 76 and there are 34 yes responses and 42 no responses. |
| 5) As provided the information is not very interesting. This question had 74 responses of 1 and 2 responses of 2. The mean is 1.026 The median and mode are both 1. The range is [1, 2]. The minimum is 1 and the maximum is 2. |
| 6) For this one all recorded responses were 1. The mean, median, and mode are all 1. The range is [1]. The minimum and maximum are both 1. The histogram is a single bar. |

Target Population:
The target population is people of all ages, young to old. People who have college degrees as well as those who haven’t finished high school would qualify for this survey. They could be working professionals or low wage workers. Lastly, they may or may not be very familiar with space exploration events. Pretty much, everyone who is human and has had exposure to media or education can qualify for this survey. Anyone who has ever heard or watched a movie about aliens would qualify.
Everyone should be included in this study because everyone on this planet could be affected by the discovery of other life forms in our galaxy. Since everyone could be affected, then everyone should consider the possibility of aliens. If necessary, everyone on the planet should be prepared to meet aliens one day. There is no one who doesn’t qualify to voice their opinion on this matter.
Sampling Strategy:
Since this survey qualifies all of the human race, I’ve decided random sampling will be the easiest and most time efficient method. Hopefully, through a random sample, I can reach people of different ethnicities, educational backgrounds, religious beliefs and ages. Coordinating any other type of survey would take too much time and money. Also, it would require multiple samples from various groups. Time would have to be taken to identify and label groups as well as the samples taken from those groups. One would have just as likely a chance at an effective statistic using random data. More specifically, soliciting anyone who may or may not be interested in this survey; soliciting anyone without any kind of methodology or way of selecting people for the survey.
If the strategy isn’t right, then the results could be disproportionate to what the general population might think about the possibility of alien life. Since everyone can qualify for this survey, if I survey too many of one kind of person (of same background, education or ethnicity), then the results won’t be a good representative. At the same time, if I can’t get many different types of people to answer the survey, then I might have to re target the sample to whatever group I had the most access to. For example, if I only had access to people living in my town who were between ages of 15-60; then my survey would declare that so many people in my home town believe/don’t believe in aliens.
Survey Questions:
These questions are the best questions because they stick to the matter without any reference to bias. Also, these questions aren’t written with any bias; they use plain language so as not to influence survey takers. The answers allow for people to state plainly and without bias or other influence if they believe in aliens, don’t believe or are not sure. Lastly, the questions incorporated are those that are always associated with the topic of aliens: education, religion and personal interest in the matter of aliens. These three things are purported to influence people’s beliefs in aliens.
