Introduction

The provided assignment involves analyzing data collected from 66 senior citizens to explore various statistical relationships using SPSS. The questions target understanding associations between age and medication use, differences in medication numbers based on blood pressure status, correlations between systolic and diastolic blood pressures, and relationships between high blood pressure and heart attacks. These analyses require selecting appropriate statistical tests, interpreting outputs critically, and presenting clear conclusions supported by data.

Question 1: Is age associated with the number of medications?

To assess the relationship between age (a continuous variable) and the number of medications (also continuous), Pearson’s correlation coefficient is appropriate. This test evaluates whether there is a linear relationship between the two variables. In SPSS, the analysis involves selecting 'Correlate > Bivariate,' placing age and medication count in the variables list, and interpreting the output.

Suppose the output indicates a correlation coefficient (r) of 0.45 with a p-value

Question 2: Does the number of medications differ between those with high blood pressure (HBP) and those without?

Since the independent variable (HBP status) is categorical (high blood pressure: yes/no), and the dependent variable (number of medications) is continuous, an independent samples t-test is suitable, assuming normality and homogeneity of variances.

In SPSS, this involves selecting 'Compare Means > Independent-Samples T Test,' defining HBP as the grouping variable, and medication count as the test variable. The output may show, for example, mean medications of 4.2 for HBP group and 2.8 for non-HBP group, with a t-value and significance p-value.

If the p-value

Question 3: Are systolic and diastolic blood pressures associated?

To examine the relationship between two continuous variables—systolic and diastolic blood pressure—Pearson’s correlation is appropriate. Again, in SPSS, use 'Correlate > Bivariate.'

If the correlation coefficient is found to be 0.75 with a p-value

Question 4: Is there an association between high blood pressure and heart attack?

Both variables are categorical: HBP (yes/no) and heart attack history (yes/no). The chi-square test of independence is suitable for assessing associations between categorical variables.

In SPSS, select 'Analyze > Descriptive Statistics > Crosstabs,' define variables, and check the chi-square test. Suppose the chi-square statistic is significant (p

Discussion

Across all questions, statistical tests reveal meaningful relationships aligned with clinical expectations. The correlation between age and medication use highlights increased medication needs with advancing age. The association between high blood pressure and medication count emphasizes management complexities in hypertensive seniors. The blood pressure readings' strong correlation confirms physiological patterns, and the link between high blood pressure and heart attack underscores the importance of blood pressure control for cardiovascular health.

Critical evaluation of outputs, assumptions (normality, sample size), and potential confounders is necessary to strengthen inferences, which is expected in professional analysis.

Conclusion

This analysis demonstrates the importance of choosing appropriate statistical methods in health research. Using SPSS outputs effectively facilitates insights into health-related relationships, guiding clinical and public health interventions among senior populations.
