Lenae has collected the information she needs from her sample. Now it is time to analyze this information using the concepts of parameters and statistics.
A parameter is the characteristics used to describe a population. For example, Lenae knows one parameter of her community is that they all live in the same town. It is a 100% known parameter of the population. If Lenae was able to see a 100% accurate census in the city, she could probably find parameters such as the number of people in a specific age range in the population. It’s hard to have 100% proof of the particular characteristics of a community. It is when we use statistics.
A statistic is the characteristics of a sample used to infer information about the population. For example, Lenae is using a model to analyze data about her town’s population. Lenae has found that 64% of the people she surveyed are concerned about the safety of the town park.
Using Statistics To Understand Populations:
Lenae is campaigning for town mayor. Today, she is doing a little market research to understand the concerns of the people in her town. To collect this information, Lenae will have to understand the parameters and statistics when working with populations. Here in this article, we going to see what is the parameter of interest and its differences between statistics in clear explanation.
In this lesson, you will learn about the differences between parameters and statistics when working with data. But first, let’s review populations and samples.
5 Main Steps To Write Good Statistical Report:
The statistical report has its peculiarities. Its structure differs from the design of the other types of writing work. It has standard features like “Introduction” and “Conclusion” parts, though.
Your main task is to present the data you obtained via your researches and explain your results and which means of statistical analysis you used.
A guide on making a good statistical report includes five steps.
Step1: Write The Abstract
The Abstract is the text preface put before the standard Introduction, and you need to gain the attention of your target audience with it.
- Define the critical points of the report and its goals;
- Define the structure of the work, its parts and briefly explain the goals of each element;
- Name the main findings;
- Sum up your conclusions;
- Give a brief description of the research methods you used;
- Size – up to 200 words.
Step2: Introduction Of Statistical Report
In the Introduction, you should explain why you took this topic. If you wanted to answer some questions or prove some hypothesis, mention this. Also, give a summary of the experiments which you performed.
How to write the Statistical Report Introduction correctly: 3 main rules
Name the goal of the research. For example, fill some gap in the data, resolve a problem, disprove some statement, or else. Mention the importance of your work in this context.
Give a brief overview of the most important results.
Don’t overload your text with terms and numbers in the Introduction.
Step3: Write About Your Research Methods
In this part, you shouldn’t explain the essence of the standard statistical analysis methods; your audience has to know them by default. Instead, describe your experiments, their aims and how you compiled the data.
Mark if the task itself remained constant all the time, or you had to adapt the goals to the new conditions.
List the resources and applications you used. However, if you only worked with printed media, it is enough to list them in the bibliography.
Step4: Tell About Your Results
It is the largest and the “driest” part of the report.
Present facts only, don’t draw any analysis or discussions;
Start from the general concepts and move to particular details;
Don’t mention any irrelevant results, unless you discovered something new and unexpected;
Use terms and strict definitions, in this part you shouldn’t use conversational style;
Pay attention to the page layout – use smaller paragraphs.
Illustrate each result with a table, graph or a diagram.
Here you give a summary of your results and explain their meaning in the context of your field of study. Also, you should mention if you approved or disproved your initial hypothesis.
Note that you should use plain language in Conclusion. This part, together with the Introduction and the Abstract, should be written in the general style without problematic terminology.
If you find out in the process of the researches that the write for us subject has to explore more, note this too. Outline which methods you would use for that and which results you expect to get.
