High-Performance Liquid Chromatography (HPLC) is an advanced analytical technique used to separate, identify, and quantify components in a mixture. HPLC involves a liquid mobile phase that carries the sample through a column packed with a stationary phase. Components in the sample interact differently with the stationary phase, leading to their […]
Probability is a measure of the likelihood or chance that a particular event will occur. It is quantified as a number between 0 and 1, where 0 indicates that the event will not occur, and 1 indicates certainty that the event will occur. In mathematical terms, the probability of an […]
Correlation is a statistical measure that describes the strength and direction of a linear relationship between two variables. It is quantified using the correlation coefficient, which ranges from -1 to 1. A correlation coefficient of 1 indicates a perfect positive linear relationship, while -1 indicates a perfect negative linear relationship. […]
The chi-square test is a statistical method used to determine if there is a significant association between two categorical variables. It compares the observed frequencies in each category with the expected frequencies if there were no association. The test calculates the chi-square statistic, which measures how much the observed frequencies […]
The arithmetic mean, commonly referred to as the mean, is a measure of central tendency that represents the average value of a dataset. It is calculated by summing all the values in the dataset and then dividing by the number of values. For example, in the dataset [2, 4, 6, […]
