The Suitability of Handwashing, Age, and Gender

Sample:

A convenience sample of 100 undergraduate students from the University of Hawaii (18 to 22 years of age) was used.

Equipment:

Sink, Stopwatch

Recording Time:

Time will start when each participant’s hands are wet and will end when hands are removed from under faucet.

Statistical Procedures:

Data entry and analysis were performed using SPSS version 25.0. Descriptive statistics of mean, mode, median, standard deviation, minimum and maximum, and measures of data distribution normality were calculated to summarize the data. The hypothesis was tested within 95% confidence interval using differential analysis of chi-square tests and analysis of variance (ANOVA). Statistical correlation was used to determine the magnitude and significance of the relationship between age and handwashing time. Comparison of mean handwashing times was employed to determine if males and females handwashing times differed significantly.

Hypothesis Tested:

Null Hypothesis (H0: r = 0): There is no significant relationship between age and handwashing time.

Alternate Hypothesis (Ha: r ≠ 0): There is a significant relationship between age and handwashing time.

Null Hypothesis (H0: r = 0): There is no significant difference between mean handwashing time and being female or male.

Alternative Hypothesis (Ha: r ≠ 0): There is a significant difference between mean handwashing time and being female or male.

Hypothesis tested at the 0.05 level of significance.
