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.
A deck more than 2 feet or two steps above ground must have a railing. Codes dictate how high the railing must be, as well as how far apart the balusters can be. Small children must not be able to climb it. Some codes require handrails, not just cap rails, for stairs.
