In this article, you will learn about some of the useful concepts in statistics like quartiles and the Interquartile Range (IQR). These concepts allow graphical representation of several probability distributions and also help create box and whisker plots, which are an effective way to represent and compare data.
Here, in particular, you would be learning about confidence intervals – what is a confidence interval, what is the process of constructing confidence intervals, the difference between one-sided confidence interval and two-sided confidence interval and most importantly, how to interpret confidence intervals?
While you are learning statistics, you will often have to focus on a sample rather than the entire population. This is because it is extremely costly, difficult and time-consuming to study the entire population. The best you can do is to take a random sample from the population – a sample that is a ‘true’ representative of it.
In statistics, descriptive data analysis must always be done first before anything else. This is done so that you can get to know your data, find errors in data collection and data entry, and to find out basic information such as the central tendencies and dispersion characteristics of data. There are many different ways to get to know data, and you are probably most familiar with calculating central tendencies and measures of dispersion.
Standard deviation is used to test variability in statistics by calculating the average distance from the mean of all the values in a data set. Another way to think of it is to ask, “How much do the values in this data set deviate from the mean value?”
