A Short Guide on What Is Statistics
Various disciplines lie within Statistics. It encompasses scientific fields like Physics, Chemistry, and Biology, as well as social and life sciences. Its aim is to find patterns in data and to analyze them to obtain information that can be used to develop novel hypotheses. In this article, we shall consider some of the basic features of statistics. This will help you understand what is required of you when working on a lab report in statistics.
The Fundamental Concepts
Unless you are a science student, you will not have to memorize a lot of statistics. However, you will interact with some statistical concepts frequently. Therefore, you should be keen when grasping the relevant concepts. For instance, one of the first things to remember is that statistics involves numbers. There can be different kinds of numbers, including numerical, which can be positive or negative.
Another fundamental concept is statistics of probabilities. It includes the odds that an event will occur given the available sample. For instance, you can calculate the probability of getting a positive result from a test result. Similarly, you can calculate the probability of getting a negative result. These two concepts are very important in statistics.
Another fundamental concept is called mean. It is the average value of a variable. You can consider it as the average of the collected data. You will find that the statistics you learned in class about mean and standard deviations also applies to statistics of probability.
Working with Data
The process of obtaining data is not different from that of other forms of data collection. For instance, https://www-cdn.law.stanford.edu/wp-content/uploads/2015/06/49-Criticism-687.pdf you can walk into a bar and ask for people’s daily routine. When you get the information from the customers, you can infer their demographics easily. Similarly, it is the same when you are collecting data through surveys and other forms.
The next step is to analyze the collected information to obtain meaningful information. The process involves different steps, including:
- Visual inspection – As seen earlier, you have to look at the information gathered to interpret it. In statistics, this involves examining the data to find vital information such as averages and probabilities.
- Data gathering – This involves arriving at the information you need by following the samples or the observations as they are.
- Analysis – Here, you can sort the data and also fit a distribution to it.
- Calculation of averages and probabilities – After concluding your analysis, you can use the information to calculate averages and probabilities. The calculations will depend on the kind of data and your expertise.
Following this process, you shall find that statistics is not very different from other disciplines. You will have to work with numbers, odds, and standard deviations as the data relates to them. The validity of the information obtained will depend on how you analyze it.
