Design an experiment to test whether watching tv influences kids ability to follow directions/regulate their emotions. Be sure to specify your experimental hypothesis and identify your dependent and independent variables, as well as your experimental and control conditions. Please also operationally define your variables. Identify any experimental procedures that would help to ensure the reliability of your research.

SCENARIO: A small hospital uses a standardized test to measure depression. The psychometric properties of the test are Cronbach alpha of .48 and a test-re-test of .25. The test has a concurrent validity with another well-used test of .50. With so many current concerns of depression in adolescent girls, a nurse decides to conduct a study to determine if a nationally acclaimed intervention program for depression, Live Happy, could reduce the incidence of depression. The nurse develops a proposal that...

Think of observation then form a question and hypothesis. Then,
design an experiment you could do to test your hypothesis. Make
sure the experimental design is detailed and define all of your
variables (the dependent variable, the independent variable, the
controlled variable, designing the procedure, level of treatment,
replication, the control. )

Design an Experiment Assignment Design an experiment to investigate whether the physical attractiveness of a political candidate plays a role in how they are perceived by voters. Keep in mind that you will not have to carry out the study; only design the study. Include the following pieces of information: 1) what is your research question ofinterest (eg., are the voting opinions ofyounger adult females impacted by the physical attractiveness of the candidate?) 2) What will your independent variable(s) be?...

2. Does TV make kids want to buy toys? Watching television has been linked to many problems in children, including obesity. Could it also be linked to asking for toys? How do we make children stop asking for toys? Could it be just turning off the television?

Part I. Understanding What Makes an Experiment 1) Please identify the 3 vital components of an experiment. After identifying each component, write at least one sentence elaborating on/explaining each component (10 points) Answer – The most conventional type of experiment involves three major pairs of components: independent and dependent variables, pretesting and post testing, and experimental and control groups. An experiment examines the effects of independent variable on a dependent variable. 1- Manipulate at least one independent variable. This means...

1) To test the null hypothesis in the James Bond experiment (test his claim that he can taste the difference between a Martini that is shaken and one that is stirred) you have him taste 8 shaken martinis and 8 stirred martinis, presented in a random order. How would you interpret the results of the experiment if he was correct on 0 (zero) out of 16 times? 2) An experimenter expects an effect to come out in a certain direction....

(1) determine the type of research design used (experiment, quasi-experiment, correlation, archival, naturalistic observation, etc) (2) ) identify the independent (or predictor) variable(s) and the dependent (or criterion) variable(s), (if any). A. A human resource manager was interested in determining if there was a relationship between employee satisfaction and absenteeism. The professor had 220 employees complete a test of job satisfaction and then compared the scores on this test with the number of days each employee missed work over the...
