  2. Listwise deletion - Wikipedia

    en.wikipedia.org/wiki/Listwise_deletion

    Listwise deletion will exclude these respondents from analysis. This may create a bias as participants who do divulge this information may have different characteristics than participants who do not.

  3. Extraneous and missing solutions - Wikipedia

    en.wikipedia.org/wiki/Extraneous_and_missing...

    In general, whenever we multiply both sides of an equation by an expression involving variables, we introduce extraneous solutions wherever that expression is equal to zero. But it is not sufficient to exclude these values, because they may have been legitimate solutions to the original equation.

    Then the subset is modified by "shifting forward"; that is, excluding the first number of the series and including the next value in the subset. A moving average is commonly used with time series data to smooth out short-term fluctuations and highlight longer-term trends or cycles. The threshold between short-term and long-term depends on the ...

    This process works most of the time but can also easily get confused if you have inconsistent values or additional specifiers that the system doesn't know about. To avoid this ambiguity you can force a particular data type or override the value of a cell. For numeric values, consider using template {}, see examples at Template:Val § Sorting.

    en.wikipedia.org/wiki/Interval_(mathematics)

    The Encyclopedia of Mathematics [7] defines interval (without a qualifier) to exclude both endpoints (i.e., open interval) and segment to include both endpoints (i.e., closed interval), while Rudin's Principles of Mathematical Analysis [8] calls sets of the form [a, b] intervals and sets of the form (a, b) segments throughout.
