In the Natural World, the Number of Measurable Variables That

question 19

Multiple Choice

In the natural world, the number of measurable variables that follow a normal distribution is quite remarkable.Many of these measurable variables are actually the sum of other independent variables.The Central Limit Theorem helps explain this phenomenon because:

• A) the Central Limit Theorem states that all measurable variables follow a normal distribution.
• B) the Central Limit Theorem states that for a sufficiently large number of variables, the sum of these variables will be approximately normally distributed.
• C) the Central Limit Theorem states that for large sample sizes, all measurable variables will follow a normal distribution.
• D) the Central Limit Theorem states that because nature is normative, variables found in nature will be at least approximately normal.
