Solve the questions below

Rank the scales of measurement in order from

least informative to most informative.

23. What is the main disadvantage of measuring qualitative data? In your answer, explain why quantitative research is most often applied in the

behavioral sciences.

24. State whether each of the following describes a

study measuring qualitative or quantitative

data.

a. A researcher distributed open-ended questions

to participants asking how they feel when

they are in love.

b. A researcher records the blood pressure of

participants during a task meant to induce

stress.

c. A psychologist interested in drug addiction

injects rats with an attention-inducing drug

and then measures the rate of lever pressing.

d. A witness to a crime gives a description of the

suspect to the police.

25. State whether each of the following are continuous or discrete data.

a. Time in seconds to memorize a list of words

b. Number of students in a statistics class

c. The weight in pounds of newborn infants

d. The SAT score among college students

26. Fill in the table below to identify the characteristics of each variable.

State whether each of the following is true or false.

a. Graphs, tables, and summary statistics all illustrate the application of inferential statistics.

b. Inferential statistics are procedures used to

make inferences about a population, given

only a limited amount of data.

c. Descriptive statistics can be used to describe

populations and samples of data.

13. A researcher measured behavior among all individuals in some small population. Are inferential

statistics necessary to draw conclusions concerning this population? Explain.

14. Appropriately use the terms sample and population to describe the following statement: A statistics class has 25 students enrolled, but only 23

students attended class.

15. On occasion, samples can be larger than the population from which it was selected. Explain why

this can't be true.

16. A researcher demonstrates that eating breakfast in

the morning causes increased alertness throughout the day. What research design must the

researcher have used in this example? Explain.

17. A researcher measures the height and income of

participants and finds that taller men tend to

earn greater incomes than shorter men. What

type of research method did the researcher use in

this example? Explain.

Don't forget a title that includes the independent and dependent variables and axes labels with units,For each of the following transition matrices, do the following. First specify the classes of the following Markov chains and determine whether they are transient or recurrent. Second, determine whether the Markov chain is irreducible or not. Third, if the matrix is irreducible, find the stationary distribution x. Fourth, if the Markov chain is irreducible, determine whether the Markov chain is periodic or not, and give the period. Fifth, for irreducible Markov chains, calculate the expected number of steps to return to each state when starting from the state in the long-run. Finally, using the software, find P109 approximately and check if each row matches with a for irreducible Markov chains. O 0 0 0 P = 1/2 1/2 0 0For each of the following transition matrices, determine whether the Markov chain with that transition matrix is (1) Is the Markov chain whose transition matrix whose transition matrix is 0.6 0.4 regular? (Yes or No) (2) Is the Markov chain whose transition matrix whose transition matrix Is 0.1 0.8 0.17 regular? (Yes or No) (3) Is the Markov chain whose transition matrix whose transition matrix is 0.4 0.6 regular? (Yes or No)
