The Philippine Mental Health Associations contacts 1,028 teenagers who are 13 to 17 years of age and live in Antipolo City and asked whether or not they had been prescribed medications for any mental disorders, such as depression or anxiety. ANSWER: Population: Teenagers 13 to 17 years of age who live in Antipolo City Sample: 1,028 teenagers 13 to 17 years of age who live in ______

A farmer wanted to learn about the weight of his soybean crop. He randomly sampled 100 plants and weighted the soybeans on each plant. ANSWER: Population: Entire soybean crop Sample: 100 ______ selected

Descriptive statistics describe the information collected through numerical measurements, charts, graphs, and ______. The main purpose of descriptive statistics is to provide an overview of the information collected.

In this step the information collected from the sample is generalized to the population. This process is referred to as ______ statistics.

Variables are the characteristics that differentiate every individual within the population/sample. Variables can be classified into two groups: 1.Qualitative variables is variable that yields categorical responses. It is a word or a code that represents a class or ______.

Quantitative variables may be further classified into: Discrete variable is a quantitative variable that either a finite number of possible values or a countable number of possible values. The terms countable means that the values result from counting, such as 0, 1, 2, 3, and ______.

A continuous variable is a quantitative variable that has an infinite number of possible values that are not ______.

Nominal Level - Identify, name, classify, or categorize objects or events. Example: Method of payment (cash, check, debit card, credit card), Type ______.

Variables are the characteristics that differentiate every individual within the population/sample. Variables can be classified into two groups: 1.Qualitative variables is variable that yields categorical responses. It is a word or a code that represents a ______ or category.

In this step the information collected from the sample is generalized to the population. This process is referred to as ______ statistics.

Statistics is the science of collecting, organizing, summarizing, and analyzing information to draw conclusions or answer questions. What information is referred to in the definition?

A researcher must determine the question(s) he or she wants answered. The question(s) must be detailed so that it identifies a group that is to be studied and the questions that are to be answered. The group to be studied is called the ______.

Gaining access to an entire population is often difficult and expensive. In conducting research, we typically look at a subset of the population called a ______.

Universe is the set of all entities under study. Population is the set of all possible values of the variable. An individual is a person or object that is a member of the ______ being studied.

Sample is the subset of the universe or the population. A research objective is presented. Identify the research ______.

According to the Merriam Webster dictionary, data are 'factual information used as a basis for reasoning, discussion, ______'.
