This week, complete your Signature Assignment, which will require you to design a research survey tool that utilizes a quantitative design. Be sure your Signature Assignment will include the following parts: Introduction (3-4 pages) Describe the construct under examination. Explain why it is important to examine it and the consequences of not doing so. Include a minimum of three citations to relevant scholarly sources. Method (3 pages) Describe the participants, instrument, and procedure used to construct the instrument. Steps (3 pages) Assume a factor analysis has been completed and the instrument has been developed, assess the reliability and validity. Discuss the steps that you should take to assess the reliability and validity of the instrument. Describe the steps that should be taken to avoid bias. Describe the steps that should be taken to ensure that ethical guidelines are followed. Issues (2 pages) Describe administration issues that you must overcome. Results (3 pages) Describe the types of analysis you would use and suggest what results likely would be seen. Discussion (2-3 pages) Evaluate the properties of the instrument, how you would revise or improve it, and recommendations for further study of the instrument. Reference List Include at least 10 scholarly sources in your paper.

Running and sleep. sufficient sleep is important for adolescents for both their neural and psychological development. despite this, daytıme sleepiness and poor physical and psychological functioning related to chronic sleep disturbances are common. there is a growing body of evidence that exercise is associated with both better sleep and improved psychological functioning sixty participants were recruited from a high school in northwesten switzerlandthey were randomly assigned to either a running group or a control group, 30 to each group the running group ran every moming for a little over 30 minutes on weekdays for a three-week period. all participants used a sleep log for subjective evaluation of sleep, and sleep was also objectively assessed at the beginning and end of the study using a sleep electroencephalographic device that measured quantities such as sleep efficiency and time spent in the four different sleep phases. running was found to have a positive impact on both objective and subjective measures of sleep functioning what are the explanatory variable(s) and the response variable(s)? (a) outline the design of the experiment (b) (c) here are some more details on the treatment and control groups. all participants arrived at school at 7 a.m., and the running group did two laps on the track and then ran cross countrv in groups of at least four people for 30 minutes the control group remained seated at the track, worked on horpework. and interacted with each other. when the runners returned, all participants prepared for school and ate a breaktast that was provided. iwhy do you think the experimenters had the control group arrive at 7 am interact withdassmates and have breaktast together? explain. do you think having the control eroup do these activities is important for the types of conclusion that can be reached? how?
