Data analysis biostatistics

1. Calculation of descriptive statistics

a. Create a bar chart for the participants’ gender and ethnicity.

The results indicated in the bar chart below show that most respondents; 18 (60%) were females compared to the male colleagues accounting for 12 (40%), (David, 2017).

In addition, the results on the ethnicity indicate that most respondents; 14 (46.67%) were Whites followed by the Black Americans accounting for 8 (26.67%). Additionally, the Black and Other ethnics accounted for 5 (16.67%) and 3 (10.0%) respectively, (Opie, 2019).

b. Create a histogram for participants’ age

The mean age is 27.9 with a standard deviation of 9.63. The age is positively skewed with the normal curve drawn, (Campbell, 2016).

2. Calculate descriptive statistics for your dependent variable

The results in the table below indicate that a majority of the respondents; 19 (63.3%) were satisfied with the current VTE risk assessment while only 11 (36.7%) were not satisfied with the current VTE assessment, (Guerrero, 2019).

4. Hypothesis formulation and testing
a. An independent samples t-test was used to test the hypothesis listed below.

b. Write the null and alternate hypotheses.

Null hypothesis: There is not a statistically significant mean difference in age for those satisfied with the current VTE risk assessment and those not satisfied with the current VTE risk assessment.

Alternative hypothesis: There is a statistically significant mean difference in age for those satisfied with the current VTE risk assessment and those not satisfied with the current VTE risk assessment.

Equal variances not assumed					-5.321	11.409		.000		-15.373	2.889		-21.705		-9.042

c. What is the calculated statistic value?

The calculated statistic value when the equal variances assumed is -6.644
d. What is the p and critical statistic value?

The p and critical statistic value are 0.0005 and 6.28, respectively.
e. Is the p value significant? Is calculated statistic value greater than critical value?

Yes, the p value calculated is highly significant; p-value<0.05. However, the calculated statistic value is lower than critical value; -6.644<6.28, (Anderson, et, al, 2020).
f. What is your conclusion?

In conclusion, The mean of the participants not satisfied with the current VTE risk assessment; 37.64 with a standard deviation of 9.26 is higher than the mean of the participants satisfied with the current VTE risk assessment; 22.26 with a standard deviation of 3.21. Hence, we reject the null hypothesis and conclude that there is a statistically significant mean difference in age for those satisfied with the current VTE risk assessment and those not satisfied with the current VTE risk assessment, (Anderson, et, al, 2020).
