Descriptive statisticsare used to describe a chunk of raw data. There are three main types of descriptive statistics: 1. Summary statistics 2. Charts 3. Tables Each of these can help us gain a better understanding of existing data. For example, suppose we have a set of raw data that shows the test scores of 10,000 students in a certain city. We can...
There are more charts being generated in journals, news outlets, online articles, and magazines than ever before. Unfortunately, charts can often be misleading if you don’t understand the underlying data. For example, suppose some journal publishes a study that finds a negative correlation between GPA and ACT scores for students at a a certain univ...
One important concept that you’ll learn about in statistics is the concept of confounding variables. These are variables that are unaccounted for and can confoundthe results of an experiment and lead to unreliable findings. For example, suppose a researcher collects data on ice cream sales and shark attacks and finds that the two variables are high...
One of the most important sub-fields of statistics is probability. This is the field that studies how likely events are to happen. By having a basic understanding of probability, you can make more informed decisions in the real world. For example, suppose a high school student knows that they have a 10% chance of being accepted to a given universit...
Another important concept that you’ll learn about in statistics is p-values. The textbook definition of a p-value is: For example, suppose a factory claims that they produce tires that have a mean weight of 200 pounds. An auditor hypothesizes that the true mean weight of tires produced at this factory is different from 200 pounds so he runs a hypot...
Another important concept that you’ll learn about in statistics is correlation, which tells us the linear association between two variables. The value for a correlation coefficient always ranges between -1 and 1 where: 1. -1 indicates a perfectly negative linear correlation between two variables 2. 0 indicates no linear correlation between two vari...
Another important reason to learn statistics is to understand basic regression models such as: 1. Simple linear regression 2. Multiple linear regression 3. Logistic Regression Each of these models allow you to make predictions about the future value of some response variablebased on the value of certain predictor variables in the model. For example...
Another reason to study statistics is to be aware of all the different types of bias that can occur in real-world studies. Some examples include: 1. Observer Bias 2. Self-Selection Bias 3. Referral Bias 4. Omitted Variable Bias 5. Undercoverage Bias 6. Nonresponse Bias By having a basic understanding of these types of biases, you can avoid committi...
Many statistical tests make assumptions about the underlying data under study. When reading the results of a study or even performing your own study, it’s important to understand what assumptions need to be made in order for the results to be reliable. The following articles share the assumptions made in many commonly used statistical tests and pro...
Another reason to study statistics is to understand the concept of overgeneralization. This occurs when the individuals in a study are not representativeof the individuals in the overall population and therefore it’s inappropriate to generalize the conclusions from a study to the larger population. For example, suppose we want to know what percenta...
Advantages of Statistics. Making sense of data – Statistics helps us understand and make sense of large amounts of information, like how many kids in your class like pizza or how many times a day the average person smiles.
Using appropriate statistics, you will be able to make sense of the large amount of data you have collected so that you can tell your research story coherently and with justification. Put concisely, statis-tics fills the crucial gap between information and knowledge. A very brief history of statistics.
Instant Results: With StatCalculator.net tools, you can obtain statistical results within seconds. Wide Range of Calculators: Our calculators provide everything from basic calculators like mean, median, and standard deviation to advanced tests like t-tests, ANOVAs, and regression analysis.
Oct 16, 2020 · From imaging black holes and predicting the weather to discovering genes and tackling the COVID-19 pandemic, statistics helps us understand data so we can make sense of the universe: and make more informed decisions. For World Statistics Day, we asked Royal Statistical Society ambassador Dr Anthony Masters to help us demystify statistics.
