Interval-censored observations : Interval-censored observations refer to data where the exact value of a variable is not known, but rather a range within which the value is believed to fall. For example, consider a study on the lifespans of a particular species of bird. If a researcher were to observe a bird that is estimated […]

Interruptible designs : Interruptible designs are a type of system or design that allows for the interruption of a process or operation in order to perform a higher priority task. This is often used in computing and control systems in order to efficiently allocate resources and prioritize tasks. One example of an interruptible design is […]

Interrupted time series design : An interrupted time series design is a type of quasi-experimental research design in which a treatment or intervention is applied to a population at a specific time, and the effect of this intervention is measured by comparing the changes in the outcome variable(s) before and after the intervention. This design […]

Interquartile range : The interquartile range (IQR) is a measure of the dispersion of a dataset. It is calculated as the difference between the 75th and 25th percentiles of a dataset. These percentiles are also known as the first and third quartiles, hence the name of the measure. For example, consider the following dataset: 1, […]

Interpretability : Interpretability is a crucial aspect of many decision-making processes, particularly in fields such as artificial intelligence (AI) and machine learning. It refers to the ability to understand and explain the reasoning behind the decisions made by a model or algorithm. One example of interpretability in action is in the field of healthcare. When […]

Interpolation : Interpolation is a mathematical method that is used to estimate a value within the range of a set of known data points. It is often used in computer graphics, signal processing, and other mathematical and scientific fields. One example of interpolation is when you have a set of data points that represent the […]

Interior analysis : Interior analysis is a method used in regression analysis to assess the quality of a model. It involves looking at the relationships between different predictor variables and the dependent variable, and determining how well the model captures these relationships. To understand how interior analysis works, let’s consider a simple example. Suppose we […]

Interim analyses : Interim analyses are periodic evaluations of data that are conducted during a clinical trial. These analyses are used to assess the safety and efficacy of a treatment being studied, as well as to make any necessary adjustments to the trial design. Interim analyses can be performed at any point during a clinical […]

Intercropping experiments : Intercropping is a farming technique that involves planting two or more crops in the same field, in close proximity to each other. This method has been used for centuries to increase the yield and productivity of a given area of land, and is particularly effective in regions with limited land resources. One […]

Intercept : Intercept in regression analysis refers to the point at which the regression line crosses the y-axis. This is the point at which the predicted value of the dependent variable is zero, even when all predictor variables are at their minimum values. For example, consider a regression analysis of the relationship between the amount […]
