What data can have only 2 values?
A binary variable.
What is Continuous data in statistics?
It means numerical data which can hold any value . For instance, human height is continuous. There is no set of allowable heights. It can be any number. In contrast, human sex (i.e male or female) is categorical data, because there are only two possible values.
Is it possible for the standard deviation of a set of data to be zero?
Yes, but only if every element in the data set is exactly the same. Therefore, very unlikely.
Which measure summarizes all of the values of a data set with a single number?
The central tendency can be summarised by the mode, median or mean. For qualitative data, only the mode is available.The central tendency can be summarised by the mode, median or mean.

What does discrete data mean in maths?
Discrete - Each recorded data has a particular whole value e.g. Number of pencils in pencil cases, Number of correct answers in a test Continuous - The recorded data can have any value in a given range e.g. Height of students, Time taken to run 100m
What is data that can only be one of two possible values?
A binary variable.
What are logical functions?
A logical or boolean function is one that works with logical or boolean values - values that can only be either true, or false.
Can Worksheet cells only contain numbers?
No. A worksheet can hold all sorts of data, like text, dates, number, logical values and formulas.
What is logical file?
Logical file is a type of file that provides a view of the data stored into the Physical file. It does not contain data. A logical file contains only an index to the data stored into the physical file.
Which one between logical and physical data independent is harder to achieve and why?
the logical data independence is hard to achieve because all the manipulation is belonging in logical data independence but in physical data independence only show the physical view .
The hyperlink data type stores data that can have one of two values?
yes/no data type stores only one oftwo values
Which data type stores only one of two values?
In Java, such a data type is called boolean. In other programming languages it may be known by different names, including variations of "boolean" such as "bool", and "logical".
Is it possible to calculate the coefficient of variation using relative values instead of absolute values?
The coefficient of variation should be computed only for data measured on a ratio scale, as the coefficient of variation may not have any meaning for data on an interval scale. Using relative values instead of absolute values can cause the formula to give an incorrect answer.
Does The COUNT function in Excel returns the number of all cells in a range that contain any type of data?
No. The COUNT function counts only numeric values, including dates and times. It will not count cells with text or logical data or blank cells. COUNTA will count all kinds of data.
What data can have only 2 values?
A binary variable.
Difference between relational and logical operators?
Logical operators don't Compare values they combine Boolean values and produce a Boolean result. Examples of logical operators are && (and), , (or), ! (not). If you have two Boolean values and you combined them with the && operator the result will be (TRUE) only if both values were (TRUE). Relational operators compare two values and produce a Boolean result. Most of the time we use logical operators to combine the results of two or more comparison expressions that use relational operators.
A query is sometimes called a logical view of data because?
Queries do not store Is_A_query_datasheet_is_called_a_logical_view_of_the_data_because_a_query_does_not_physically_store_the_data_as_it_is_still_stored_in_the_tables, they only display a view of data.
