population estimation
Which of the following is a discrete variable?
it may not have been a score actually in the distributionExplanation / Answer
1) All of the following statements about the median are true, except it is appropriate for all measurement scales.
2) n a positively skewed distribution, the mean is typically greater than the median.
3) In APA journal articles the Results sections usually report the mean and the SD of the data.
4) A clinical psychologist studying the effects of different therapies categorizes patients according to whether or not they are in therapy. In this case, therapy is a qualitative variable.
5) If you were interested in studying the effects of varying preparatory instructions on the perception of pain during an injection, the instructions would be an independent variable and the amount of perceived pain would be a dependent variable.
6) Interval measures have the property that numerically equal distances on the scale represent equal distances on the dimension being measured.
7) A continuous variable can theoretically include an infinite number of values between any two points.
8) Taking measurements on a sample and then, from observations, inferring something about a population is known as inferential statistics.
9) Which of the following is a discrete variable?
Number of children.
