   'Measurement skills and concepts' or 'Spatial Sense' are directly related to the world in which students live. Many of the concepts that students are taught in this strand are also used in other subjects such as science, social studies, and physical education [ 3 ] In the measurement strand students learn about the measurable attributes of ...

3. Estimation theory - Wikipedia

   en.wikipedia.org/wiki/Estimation_theory

   Estimation theory is a branch of statistics that deals with estimating the values of parameters based on measured empirical data that has a random component. The parameters describe an underlying physical setting in such a way that their value affects the distribution of the measured data.

4. Estimation - Wikipedia

   en.wikipedia.org/wiki/Estimation

   Estimation (or estimating) is the process of finding an estimate or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available. [ 1 ]

5. Method of moments (statistics) - Wikipedia

   en.wikipedia.org/wiki/Method_of_moments_(statistics)

   In statistics, the method of moments is a method of estimation of population parameters.The same principle is used to derive higher moments like skewness and kurtosis. It starts by expressing the population moments (i.e., the expected values of powers of the random variable under consideration) as functions of the parameters of interest.

6. Estimator - Wikipedia

   en.wikipedia.org/wiki/Estimator

   Bias is a property of the estimator, not of the estimate. Often, people refer to a "biased estimate" or an "unbiased estimate", but they really are talking about an "estimate from a biased estimator", or an "estimate from an unbiased estimator". Also, people often confuse the "error" of a single estimate with the "bias" of an estimator.
