The range of infrared carrier frequencies that a remote control is capable of learning or controlling. Most remotes operate between 30 and 60kHz, however some use higher and are thus known as high frequency. See also: learning, high frequency.
Or frequency distribution: in a survey, a table showing what number (or percentage) of respondents gave each answer to a question. Also called marginals or top-line results. Here's an example of a frequency distribution that matches the above cross-tab. Age group Total Age under 25 35 Age 25 to 44 39 Age 45 or above 26 Total 100
(Also called "marginals.") In survey research, the number of respondents who responded to each of the possible answers to a question. Often codebooks list the frequency of response to each question. So, for instance, you might be able to tell from a codebook how many House Members voted in favor of a bill and how many voted against it.
are counts of the number of students or persons who receive a specific score, or whose scores fall within a predetermined interval or grouping.
