std

Example:The linear regression coefficients and the R-squared were calculated from the std. deviation between the predicted and actual values.

Definition:The standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of data values. A low standard deviation indicates that the data points tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the data points are spread out over a wider range.

Example:The std. time in China is GMT+8.

Definition:Standard time refers to the official time of a particular area or region, especially as maintained by government or national regulatory bodies. It is the official measure of time based on the position of the sun or atomic clocks, and it is used to govern the running of everyday activities such as transportation, business operations, and public events.

Example:The hotel offered a std. room to the couple for their two-night stay.

Definition:A standard room is a type of room that is a typical size and layout in a hotel, apartment building, or any other type of accommodation. It is usually furnished in a standard way to meet the general needs of the guests.

Example:The std. error of the sample mean was found to be 0.5.

Definition:Standard error is the standard deviation of the sampling distribution of a statistic. The standard error is an important measure of the precision of an estimate. It is used to determine the accuracy of the sample mean compared to the population mean.

Example:The std. length for the screws in the assembly was 50mm.

Definition:Standard length in geography or cartography is the standard or standard-sized length of any piece of a specified and standard product, such as a pipe, a rod, or a piece of furniture. Standards of this kind ensure uniformity and simplicity in measuring, cutting, and fitting.
