Raw score. In statistics and data analysis, a raw score is an original datum that has not been transformed. This may include, for example, the original result obtained by a student on a test (i.e., the number of correctly answered items) as opposed to that score after transformation to a standard score or percentile (%) rank or the like. Often the conversion must be made to a standard score before the data can be used. For example, an open ended survey question will yield raw data that cannot be used for statistical purposes as it is; however a multiple choice question will yield raw data that is either easy to convert to a standard score, or even can be used as it is.
A standard railing shall consist of top rail, intermediate rail, and posts, and shall have a vertical height of 42 inches nominal from upper surface of top rail to floor, platform, runway, or ramp level. The top rail shall be smooth-surfaced throughout the length of the railing.
Deck Railing Codes All decks higher than 30 above grade must have a guardrail. If you choose to install a guardrail on a deck lower than 30 you must still meet code requirements. Decks attached to single family detached homes are regulated under the rules of the International Residential Code (IRC). The IRC requires guardrails to be at lest 36 in height measured from the deck surface to the top of the rail.
