I. MEASUREMENT WORKSHEET
Answer each question with respect to your team’s specific choices for the research study (this means the study as your team has decided to analyze the data, which will not necessarily be the same as the originally designed study). If you don’t recall the statistical information from your prerequisite statistics class, you may need to read ahead to information in Week 5 to answer the statistical questions. See the related Muddy Concept presentations as well. (12 points total)
1. Independent Variable:
a. What is the independent variable (IV) you have chosen for your study?
Sensory Modes
b. What is the scale of measurement for your IV? Nominal scale
c. What is the operational definition for your IV?
Levels of numerical sequence recall:
1. Auditory
2. Visual
2. Dependent Variable:
a. What is the dependent variable you have chosen for your study (DV)? Numerical Memory
b. What is the scale of measurement for your DV?
Ratio Scale
c. What is the operational definition for your DV?
Using an APA Online Psychology Lab study, Numerical Memory. The order of task presentation is randomized for each participant. The numerical information is measured by presenting a sequence of numbers in random order for each participant. The length of the sequence starts with one digit at the first level and adds one digit after each level
3- How would you make it an experimental (rather than correlational) study (it might help to be specific here as well and define the two types of studies in your

Memory span is a measure of short term memory and its capacity through the use of a list. Participants are asked to review a list of items, retain, and immediately recall as accurate as possible. The list may be conducted with a random list of numbers, words, or letters since these items may influence differently amongst each participant. The list is also varied in item length to test in which particular length the participant is subject to make the least of errors and determine their memory span. The average short-term memory capacity is ranged
Part B: How might each of the following concepts affect the results of the study?
2. Choose one of the research questions from above and consider it in more detail. Based upon the question, what would be a reasonable hypothesis?
Every outline heading and subheading must include a two to three sentence description. Additionally, for each study, indicate how it will support the overall concept of your Final Paper and which areas of the Final Paper it will apply to. Your assignment must include a reference page listing the three to five quantitative research studies from peer-reviewed sources that were published within the last five years (these will also be used for your Final Paper). It must be formatted according to APA guidelines as outlined in the Ashford Writing Center.
6) Prepare the survey for analysis. Set up the code sheet for this study. How will this study be set up to be tabulated by a statistical analysis program like SPSS?
This lesson allows you to elaborate on the work you did in Lesson 12. Using the research proposal you developed in Lesson 12 as a foundation, choose a sampling methodology that compliments your original proposal. Do not include specific questions in your proposal. Use the structure illustrated below. The proposal will be evaluated using, in part, your use of the methodologies described in the text.
Each study analysis will be 1,000-1,250 words and submitted in one document. As with the assignments in Topics 1-3, this should connect to your identified practice problem of interest.
1. Describe the context (why it was done, the general interest and what the researchers wanted to find out) of the research and research question (what is the hypothesis). /10
10) Was the sample for this study adequately described? Provide a rationale for your answer
To examine a research study thoroughly, critical thinking skills must be used. The five questions that lead to an analysis relate to what is being asked, what is the evidence, how is the evidence interpreted, what other ways could evidence be used, and what is the reasonable conclusion. These questions led me to my breakdown of the hypothetical research study.
-Why was the study conducted? –What was the margin of error? –What was the sample size? -What sampling design was used? –What was the response rate? –What was the frame that was used? -Who paid for the survey? –From the sample that was selected, what was the population?
When working with uses of statistical information there is as few topics individuals and organizations need to know and these are how are statistics used in the workplace, what is one example of descriptive statistics used in the workplace and what is one example of inferential statistics used in the workplace. Plus how is data at each of the four levels of measurement used in the workplace? If the workplace does not use all four levels, describe how such data could be used. What are the advantages of accurate interpretation of statistical information to improve decisions making in the
4. A fourth task is the construction of the specific measurement instruments. For a survey the interview guide or questionnaire is written, and the way in which the survey is to be carried out is specified. For an observational study the specific form and conditions of the observation and the types of recording processes to be used must be determined.
