Median survival time : Median survival time is a measure of the length of time that a group of individuals are expected to live after a specific event or diagnosis. It is commonly used in medical research to assess the effectiveness of a treatment or intervention, as well as to provide information about prognosis for […]

Median effective dose : The median effective dose, also known as the ED50, is a measure of the potency of a drug or other chemical substance. It is defined as the dose that produces a specified effect in 50% of the population. This measure is commonly used in pharmacology and toxicology to assess the potential […]

Median : Median is a statistical measure that refers to the middle value in a set of numbers. It is used to determine the central tendency of a dataset, and is often used to compare different sets of data or to identify trends within a dataset. For example, consider a group of 10 students who […]

Measures Of Association : Measures of association are statistical tools used to measure the strength and direction of a relationship between two variables. These measures help researchers understand the degree to which two variables are related and can provide valuable information for hypothesis testing and decision making. One example of a measure of association is […]

Measurement error : Measurement error is the difference between the true value of a quantity and the value obtained from a measurement. It is an inherent part of the measurement process and can arise from various sources, including the limitations of the measuring instrument, the skill of the person taking the measurement, and the conditions […]

Mean vector : A mean vector is a mathematical concept used in statistics to represent the average value of a set of data points. This is often represented as a vector, which is a geometric object that has both a magnitude (size) and a direction. The mean vector is a useful tool in data analysis […]

Mean squares : The term “mean squares” refers to a statistical calculation that is used to determine the difference between two sets of data. This calculation is typically used in hypothesis testing, where it helps researchers to determine whether there is a significant difference between the two sets of data. To understand how mean squares […]

Mean square ratio : The mean squared ratio (MSR) is a statistical measure that is used to evaluate the precision of an estimated quantity. It is defined as the ratio of the mean squared error of an estimator to the mean squared error of a reference estimator, with the goal of determining whether the estimator […]

Mean Squared Error (MSE) : Mean squared error (MSE) is a widely used loss function in machine learning, which is often used to evaluate the performance of a model on a given dataset. MSE is defined as the average squared difference between the predicted values and the true values. In other words, it is the […]

Mean-range plot : A mean-range plot is a type of statistical chart that shows the relationship between the mean and range of a set of data. The mean is the average of all the data points, and the range is the difference between the highest and lowest values in the data set. For example, let’s […]
