Statistics is an important mathematical field that is used to organize, analyze, and interpret data. It can be used to make predictions about the future, study trends in data, and draw conclusions from data sets. As a high school student, understanding the basics of statistics can help you make informed decisions in your daily life.… Continue reading

Statistics involve different types of data, and it is important to understand the differences between them. The main types of data used by statisticians include categorical, continuous, discrete, and ordinal data.  The type of data used in a statistical analysis will depend on the type of question being asked. Understanding the types of data used… Continue reading

Collecting data for statistical analysis is an essential step in research and data-driven decision making. The process of collecting data can be complex, but with the right methods and tools, it can be straightforward and produce meaningful results.  Data collection is the process of gathering information from sources such as surveys, experiments, and observations. The… Continue reading

Data representation is an important part of any data analysis project. There are many different ways of representing data, and choosing the right one can be tricky. In this blog post, we’ll explore some of the most common ways of representing data.  The first way is through tables. Tables are great for organizing data in… Continue reading

Descriptive statistics are a type of statistical analysis used to summarise and interpret data. They are used to describe the characteristics of a population or sample of data, such as the mean, median, mode, range, and standard deviation. They help us to make sense of our data and gain a better understanding of what it… Continue reading

Measures of Central Tendency (MCT) are a way to measure the “center” of a data set. The most common measures of central tendency are the mean, median, and mode.  The mean is the average of a set of numbers, calculated by adding all of the numbers together and dividing by the number of numbers. The… Continue reading

Probability is a mathematical concept that describes the likelihood of an event occurring. It is used in both everyday life and in statistics to determine the chances of something happening. Probability plays an important role in our decision-making process. By understanding the likelihood of an event, we can make better informed decisions.  For example, if… Continue reading

Sampling is an important tool used in the process of gathering data. It is a process of selecting a subset of a larger population, in order to obtain information about the entire population. Sampling is used to reduce the cost and time of the data collection process, while still providing accurate results.  When conducting a… Continue reading

Hypothesis testing is a powerful tool used in statistical analysis to determine whether an observed data set is consistent with a proposed hypothesis. This process is used to analyze results from experiments and surveys and make informed decisions about how to proceed. At its core, hypothesis testing involves a series of steps: formulating a hypothesis,… Continue reading

Regression and correlation are two related statistical techniques that are used to describe the relationship between two variables. Correlation is a measure of how two variables are related. It measures the degree to which one variable is related to another. It can be used to identify relationships between variables as well as to predict future… Continue reading
