C784-Applied Healthcare Statistics exam questions and correct answers| Latest 2026/2027 Rational number (aka 'fractional') Numbers that can be expressed as a fraction Integers Solid positive and negative numbers Real Numbers A real number is any number that can be placed on the number line, whether that be negative or positive, fraction or decimal. True or False? Any integer is also a whole number. This statement is false. An integer can be negative, such as the number −100-100. −100-100 is not a whole number. Read all the options before answering. −17-17 is... (a. an integer b. a rational number c. a real number d. all of the above.) d. all of the above. −17-17 is an integer, and all integers are also rational numbers, which in turn are real numbers. set In mathematics, a collection of numbers is referred to as a set* Interval An interval is a set of numbers between two specified values. An interval can be visualized as a segment of the number line. The segment of the number line above that falls between 11 and 22 is called an interval*. Discrete data Can only have certain, distinct values Is "counted" Contains unconnected points In mathematics, whole numbers, integers, and even integers are all examples of discrete sets. These sets contain unconnected elements, with gaps between each value. In statistics, some data sets will be discrete. Examples of discrete data sets are the number of adults in a household, the results of rolling two dice, and number of machines in operation, as these are distinct groups. (Looking at another set of data, consider the number of cars someone owns. It is not possible to own 3.43.4 cars; you either own three cars or four. The number of cars someone owns is an example of a discrete set of data, since the values are distinct, separate, and unconnected. Positive integers* are an example of discrete data.)
