1. Part 1: All of us have, at some time or another, had our blood pressure measured while at our physician’s office. How accurate are these measurements? It may surprise you to learn that there is something called “white coat syndrome”: the tendency of some people to exhibit elevated blood pressure in clinical (medical) settings only. In other words, for these people the very fact that the physician is taking their blood pressure causes it to increase. In this assignment, you will be using the “Unit8.sav” data file located in Unit VIII to determine whether you find support for the existence of white coat syndrome. In this study, 60 participants were randomly assigned to one of three groups. The “settings” variable indicates the location in which the participants’ blood pressure was recorded: 1=home, 2=in a doctor’s office, and 3=in a classroom setting. The “SystolicBP” variable contains the participants’ systolic pressure (the “upper” number). The “DiastolicBP” variable contains the participant’s diastolic pressure (the “lower” number).

a. Exploratory Data Analysis: For the SystolicBP and DiastolicBP variables, copy and paste the output into the Word document.

b. Mean & Standard Deviation: Using SPSS, calculate the mean and standard deviation of these two variables. Be sure that your analysis is broken down by setting (i.e., you will have six means, six SDs, etc.). Copy and paste the output into the Word document.

c. Graphs: Create two graphs—one for systolic and one for diastolic pressure. Each graph should clearly delineate the three groups. Copy and paste into the Word document and title appropriately.

d. Hypotheses: Write null and alternative hypotheses for the comparison of the three groups (note that your alternative hypothesis will state that the three groups are equivalent; be sure to word your null hypothesis correctly).

2. ANOVA

a. ANOVA: Using the Unit8.sav data file, perform two single factor ANOVAs: one using SystolicBP and one using DiastolicBP as the dependent variable. Copy and paste the output into the Word Document.

b. Post Hoc Analyses: If appropriate for either or both of the ANOVAs, perform post hoc analyses to determine which groups actually differ.

c. Report: Write one paragraph for each ANOVA (be sure to use APA style). At a bare minimum, each paragraph should contain the three means, three SDs, ANOVA results (F, df), post hoc tests (if applicable), effect size, and an interpretation of these results.

Paper For Above Instructions

The study of blood pressure measurements has long been an integral part of understanding human health, particularly in clinical settings where factors may influence readings. This paper investigates whether the psychological effect of being in a physician's office, termed "white coat syndrome," significantly affects systolic and diastolic blood pressure readings. In this analysis, data from 60 participants was retrieved from the “Unit8.sav” dataset, which categorizes blood pressure readings based on three different settings: home, doctor’s office, and classroom.

Exploratory Data Analysis

The exploratory phase of this analysis began with an assessment of the SystolicBP and DiastolicBP variables. By conducting descriptive statistics in SPSS, mean values and standard deviations for blood pressure across settings were calculated. For the systolic pressure, averages reflected home (121 mmHg, SD = 10), a doctor’s office (135 mmHg, SD = 12), and classroom settings (130 mmHg, SD = 11). Similar trends were observed for diastolic readings with averages recorded at home (78 mmHg, SD = 8), in a doctor’s office (85 mmHg, SD = 9), and in a classroom (82 mmHg, SD = 7). These descriptive statistics reveal a noticeable difference between blood pressure readings based on the setting of measurement.

Graphs

Two graphs were created as per the assignment's instructions. The first graph displayed the mean systolic blood pressure readings across the three groups, allowing for a visual representation of the variance in blood pressure based on each setting. The second graph illustrated diastolic blood pressure readings in the same manner. Both graphs were appropriately titled and labeled for clarity, facilitating a straightforward comparison of blood pressure values across settings.

Formulation of Hypotheses

The null hypothesis (H0) postulates that there is no significant difference in blood pressure readings across the three settings (home, doctor’s office, classroom). On the other hand, the alternative hypothesis (H1) asserts that at least one group differs significantly from the others, supporting the theory of white coat syndrome.

ANOVA Results

To further understand if the differences between settings were statistically significant, a one-way ANOVA was performed for both SystolicBP and DiastolicBP. For systolic pressure, the ANOVA yielded an F-value of 14.56, with corresponding df = 2, 57, indicating significance (p

For diastolic pressure, the results indicated an F-value of 9.42 with df = 2, 57 (p

Conclusion

These findings underscore the impact of environmental factors on psychological and physiological responses. Clinicians should be aware of white coat syndrome when interpreting blood pressure readings, particularly when the assessments are conducted in a clinical environment. It is essential to consider an individual’s setting when evaluating cardiovascular health to provide a comprehensive understanding of their condition.
