Data Analysis Assignment -
In this assignment, you will be with provided data in SPSS format.
Conduct specific statistical analysis procedures.
Prepare a report describing:
- Your data analysis procedures and the specific variables use in the analysis
- The results of your analysis
Present your results in appropriate tables and/or graphs.
Use the NHIS subset provided to you for 2000 to conduct the following procedures:
1. Provide a summary table for the study variables with some descriptive data about the study sample including the means & standard deviations for continuous variables (scale) and frequencies/proportions for categorical variables (nominal and ordinal). Write a paragraph or two describing the characteristics of the study participants.
2. Use the "Transform-Recode into Different Variable" function to recode DESIREWT into a new variable as follows (call the new variable BODYWEIGHT):
Underweight: 5% or more below desirable body weight (combining 1 & 2)
- Normal body weight: Within 4.9% of desirable body weight (using 3)
- Overweight: 5-19.9% or more above desirable body weight (combining 4 & 5)
- Obese: 20% or more above desirable body weight (combining 6 & 7)
- Missing: an answer of 9 (make sure on the variable view you set the "missing" at 9) Provide descriptive information for Body weight based on these transformed answers.
3. Use the "Transform-Compute Variable" function to create a new variable as follows to calculate the average exercise frequency (call the new variable AVRGEXER):
AVRGEXER= (VIGFREQW + MODFREQW + STRFREQW) / 3
Provide descriptive information for this variable in your text.
4. Examine if there's a correlation between age and exercise frequency (VIGFREQW, MODFREQW, STRFREQW, or AVRGEXER, whichever you like best). Show the two variables on a scatter plot, conduct the appropriate statistical test, and describe in your text.
5. Examine if there's statistically significant difference for males compared to females on the mean exercise frequency (VIGFREQW, MODFREQW, STRFREQW, and AVRGEXER, whichever you like best). Show a comparative box plot for exercise frequency among males versus females, conduct the appropriate statistical test, and describe in your text.
6. Examine if there's statistically significant difference in Smoking for males compared to females (Hint: cross-tabulate smoking and gender and request a Chi-square test), and present in a comparative bar chart. Present and describe the results in your text.

Find the velocity of the center of the panel
: A 45-g bullet is fired with a velocity of 400 m/s at θ = 30° into a 9-kg square panel of side b 5 200 mm. Knowing that h=150 mm and that the panel is initially at rest

How you analyzed your data and results
: BSA 410- Explain, in great detail, how you conducted your test(s) and how you analyzed your data and results. All statistical results should be provided. You may want to copy/paste results (if you used Excel) in this section.

Determine the velocity of the mass center g
: Assuming that the impact is perfectly plastic, determine the velocity of the mass center G of the panel immediately after the impact.

Provide a summary table for the study variables
: Provide a summary table for the study variables with some descriptive data about the study sample including the means & standard deviations for continuous variables (scale) and frequencies/proportions for categorical variables

Identify the business-level strategies for the corporation
: Analyze the business-level strategies for the corporation you chose to determine business-level strategy you think is most important to the long-term success of the firm and whether or not you judge this to be a good choice.

Which would be preferred to satisfy minimum area criteria
: Two different tunings of a process-control loop result in the transient responses shown in given Figure. Estimate which would be preferred to satisfy the minimum area criteria.

Actions for recruiting techniques
: As indicated in our text, there are many, many ways to recruit and sources to recruit from. How do we choose which techniques/sources are appropriate when we have a vacancy? Said another way, what things do we have to think about in order to make ..
