Explanation:

1. Facts collected for analysis are called data.
2. A tentative or initial explanation of an observation capable of being tested by experimentation is a hypothesis.
3. The sum of the data divided by the number of data entries (n), the usual measure of central tendency in normal distribution and also called an average, is the mean.
4. The act of seeing and noting an occurrence in the object or substance being studied is observation.
5. Data described in descriptors or terms rather than by numbers (think "characteristics") is qualitative data.
6. A logical and rigorous way in which to investigate, manipulate, gather, and record data is the scientific method.
7. A variable whose values are set, or systematically altered, by the investigator (also called the manipulated variable) is the independent variable.
8. A diagram or plot which displays numerical information in a way that can be used to identify trends in the data is a graph.

Answer:

1. k. Data
2. e. Hypothesis
3. b. Mean
4. a. Observation
5. c. Qualitative Data
6. i. Scientific Method
7. h. Independent Variable
8. f. Graph
