point estimate
A point estimate is a single value calculated from a sample that is used to estimate an unknown population parameter
A point estimate is a single value calculated from a sample that is used to estimate an unknown population parameter. It is essentially an educated guess or approximation of the true value of the parameter.
For example, if we want to estimate the average height of all students in a school, we could randomly select a sample of students and calculate the average height of that sample. This average height would be the point estimate of the population mean.
Point estimates are commonly used in statistics and are helpful in making predictions and drawing conclusions about a population based on limited sample data. However, it’s important to note that point estimates may not always be accurate as they are subject to sampling variability and potential biases. To assess the accuracy and reliability of a point estimate, it is common to provide a measure of uncertainty called a confidence interval alongside the estimate.
