(2.) Which of the following is a type of question used in survey research?

The correct answer is Option (D): All of the other answers are correct

The given three types of questions dichotomous, free response and rating are used in survey research.

The dichotomous or closed end question is a question which can have two possible answers which are usually used in a survey that asks for a Yes/No, True/False or Agree/Disagree answers.

Free response or open-ended questions ask people to provide answers in their own words and are designed to get more information than is possible in a multiple choice or other closed-ended questions.

Rating scale questions (sometimes referred to as ordinal questions) is a type of survey question that displays a scale of answer options from any range (0 to 100, 1 to 10, etc.). The respondent selects the number that most accurately represents their response.

Thus the given three questions are types of questions used in survey reserach.

(3.) The two types of quantitative variables are

The correct answer is Option (D): interval and ratio.

Quantitative variables are variables that are measured on a numeric or quantitative scale. The two types of quantitative variables are interval and ratio variables.

The interval scale is defined as a quantitative measurement scale where the difference between 2 variables is meaningful and the ntervals have the same interpretation throughout. For example, consider the Fahrenheit scale of temperature. The difference between 30 degrees and 40 degrees represents the same temperature difference as the difference between 80 degrees and 90 degrees. It do not have a true zero point.

A ratio scale is a numerical or quantitative scale with a true zero point and in which a given size interval has the same interpretation for the entire scale. Weight is a ratio scale.

(4.) Which of the following is not a method of predictive analytics?

Bullet graphs are a variation of a bar chart developed by Stephen Few as a replacement for gauges and meters which is used to compare one value, represented by a horizontal bar, to another value, represented by a vertical line, and relate those to qualitative ranges.
