What is Standard Deviation? Standard deviation (SD) is a crucial statistic that measures how dispersed data points are within a dataset. It is expressed as σ (sigma) for populations and s (small sigma) for samples. In essence, it is the average squared difference between each data point and the data set mean (average). A higher … Read more
What is Sample Variance? In statistics, sample variance (s²) plays a crucial role in understanding how spread out data points are within a sample. It reflects the average squared distance of each data point in the sample from the sample mean (x̄). A higher variance indicates a wider spread of data points, while a lower … Read more
In this article, we will master data structuring with Pandas DataFrames! Explore accessing data, modifying columns, rows, and indexing techniques for efficient data analysis in Python. What is a Pandas DataFrame? Think of a DataFrame as a two-dimensional labeled data structure, like a spreadsheet with rows and columns. Each column represents a specific variable, and … Read more
Before we dig into understanding normal distribution, we should first take a look at what distribution is? What is distribution? Distribution is a function that describes how the values of a variable are spread throughout the dataset. It reveals the possibility or frequency of each possible value occurring. For example, Imagine measuring the heights of … Read more
What is Probability? Probability refers to the chance or likelihood of a particular event taking place. It’s a numerical measure between 0 and 1 that expresses how probable an event is. The closer a probability is to 1, the more certain the event. Conversely, a probability closer to 0 indicates a less likely event. What … Read more
