For the Metric Variable of number of adults in household (ADULTCT), the descriptive statistics is below: The metric variable of number of adults in household show N=51451 with missing value of 136. The values for the mean, median and mode for this statistics are 3.64, 3.00, and 2. The std. error of mean is minute […]
Many of our today’s knowledge of facts and findings are being achieved via the burden of experimentations and making quantities or measurements. Some of the measurements done by other researchers may be called unaccepted value of error or may have missing data. However, I believed errors can occur in many aspects of conducting research. For […]

The hypothesis or alternate hypothesis is usually hidden in a word problem, and is sometimes a statement of what you expect to happen in the experiment or a claim of what will happen. Null hypothesis is statement of what will happen if the hypothesis or alternate doesn’t come true. Null hypothesis is the opposite statement […]
Statistically significant means a result is unlikely due to chance. The p-value is the probability of obtaining the difference we saw from a sample (or a larger one) if there really isn’t a difference for all users. A conventional (and arbitrary) threshold for declaring statistical significance is a p-value of less than 0.05. Statistical significance […]
To determine whether a result is statistically significant, a researcher would have to calculate a p-value, which is the probability of observing an effect given that the null hypothesis is true. The null hypothesis is rejected if the p-value is less than the significance or α level. Just because you get a low p-value and conclude a difference is […]
A general discussion of significance tests for relationships between two continuous variables. Factors in relationships between two variables The strength of the relationship: is indicated by the correlation coefficient: r but is actually measured by the coefficient of determination: r2 The significance of the relationship is expressed in probability levels: p (e.g., significant at p =.05) This tells how unlikely a given correlation coefficient, r, will […]

It is important to first understand what an acquired brain injury is. Acquired brain injury is a type of brain impairment that happens after birth, which is not connected to an inherited or worsening disease (Powell River Brain Injury Society, n.d.). Twenty-four community college study with acquired brain injury filled out questionnaires and other standardized […]
