Explain the difference in these two readings. 8. In the legend beneath Figure 2, the authors give an equation indicating that diastolic blood pressure is DBP = 25.8 + 0.13x. If the value of x is postnatal age of 30 hours, what is the value for Yˆ for neonates ≤ 1,000 grams? Show your calculations.
Since length of labor provides interval/ratio data so Range can also be used to analyze the data. 4. The distributions of scores in control and experimental groups for the length of labor are not similar neither it is significantly different for the groups. The mean (M) for the length of labor indicates (12.79 control group and 14.63 experimental group), 1.84 variation. The standard deviation (SD) for the length of labor indicates (7.78 experimental group and 7.2 control group), a variation of 0.58.
(c) Suppose that the social researcher decided to use gender as a distinct feature. Also suppose that the population X consists of m males and f females (where m+f = X), then the relative size m/X and f/X is used for proportionate allocation. Suppose Y samples must be selected for this study, and then mY/X and fY/X is to be selected within respect stratum. Random sampling can be used within each stratum. (d) There should be 6 variables in her data set, namely, Household Residents, Full Time Workers, Number of Children, Proportion of Females, Household Income and Visits made to centre.
Explain why both the naturalness of the research setting and the degree of experimental control are important variables in evaluating or deciding on a research method. 6. Describe how you could use three different research methods to test the question: does social support result in better job performance? Be sure to state your IV’s and DV’s and describe the strengths and weaknesses of each approach. 7.
1. The researchers analyzed the data they collected as though it were at what level of measurement? a. Nominal b. Ordinal c. Interval/ratio d. Experimental 2. What was the mean posttest empowerment score for the control group? The mean/average posttest empowerment score for the control group was 97.12.
NU310_Unit7_Assignment_Worksheet Guidelines for Critiquing Data Quality in Quantitative Studies 1. Is there congruence between the research variables as conceptualized (i.e., as discussed in the introduction of the report) and as operationalized (i.e., as described in the method section)? (1 point) There is congruence between the research variables in this study, five exploratory maximum likelihood factor analysis models were used in this study. 2. If operational definitions (or scoring procedures) are specified, do they clearly indicate the rules of measurement?
1. Which type of research includes an array of interpretative techniques which seek to describe, decode, translate, and otherwise come to terms with the meaning of certain phenomena? • Qualitative • Quantitative • Descriptive • Statistical 2. Which term below refers to the descriptors of variables computed from sample data used to estimate those same variables in the population? • Population parameters • Standard errors • Systematic estimates • Sample statistics Find the Latest Final Exam answers here QNT 565 Final Exam (Latest) 3.
When you add the values 3, 5, 8, 12, and 20 and then divide by the number of values, the result is 9.6. Which term best describes this value: average, mean, median, mode, or standard deviation? Answer: 9.6 is the average of the numbers listed and is also the mean of this data. 4. Answer the next four questions using the following set of numbers.
Was this an expected finding? Provide a rationale for your answer. The mean baseline depression score of the experimental group is 14.00 and the mean posttest depression score of the experimental group is 13.36. The posttest score is 0.64 lower than the baseline score. This was expected as the experimental group finished the six week empowerment program.
Comparison of Assessment Tool Constructs u06a1 Assignment Brenda J. Owens COUN5106 – Assessment, Tests, & Measures 700 Tyrone Avenue Wilmington, DE 19804 Telephone: (302) 482-3624 Email: BOWENS2@CAPELLAUNIVERSITY.EDU Instructor: Dr. Stephanie Warren Abstract The purpose of this paper is to select two assessment instruments that purport to measure the same construct. The two assessment instruments selected for this paper are the Marital Satisfaction Inventory (MSI-R) and the Dyadic Adjustment Scale (DAS). Both of these instruments measure overall relationship adjustment and satisfaction in either married, unmarried and cohabitating couples. Both assessment instruments will be compared on the basis of key test measurement concepts of reliability and validity. In addition, the learner will evaluate which assessment tool is a stronger assessment instrument using measurement concepts based upon the review of the literature.
