Answer 1

Answer:

Kinds of Linguistic Deviation          Leech divides deviation into eight types: lexical deviation, grammatical deviation, semantic deviation, phonological deviation, graphological deviation, dialectal deviation, deviation of register and deviation of historical period.

Answer 2

Answer:

A deviation that is a difference between an observed value and the true value of a quantity of interest (where true value denotes the Expected Value, such as the population mean) is an error.

A deviation that is the difference between the observed value and an estimate of the true value (e.g. the sample mean; the Expected Value of a sample can be used as an estimate of the Expected Value of the population) is a residual. These concepts are applicable for data at the interval and ratio levels of measurement.

Unsigned or absolute deviation Edit

See also: Average absolute deviation and Least absolute deviation

In statistics, the absolute deviation of an element of a data set is the absolute difference between that element and a given point. Typically the deviation is reckoned from the central value, being construed as some type of average, most often the median or sometimes the mean of the data set:

{\displaystyle D_{i}=|x_{i}-m(X)|,}{\displaystyle D_{i}=|x_{i}-m(X)|,}

where

Di is the absolute deviation,

xi is the data element,

m(X) is the chosen measure of central tendency of the data set—sometimes the mean ({\displaystyle {\overline {x}}}{\overline {x}}), but most often the median.
