Concept explainers

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

7. Effect size - Cohen's d and r squared
An industrial/organizational psychologist has been consulting with a company that runs weekend job-seeking workshops for the unemployed. She
collected data on several issues related to these workshops and, after conducting statistical tests, obtained statistically significant findings. She needs
to find a way to evaluate effect size so that she can make recommendations to the company.
One of the psychologist's findings is that six months after the workshop, a sample of 81 job seekers who received training on resume writing worked
more than 30 hours per week an average of 8.7 months in the last year, with a standard deviation of 4.1. The typical job seeker works 7.4 months.
The psychologist finds that the estimated Cohen's d is 2.853 v
the t statistic is 2.83, and r² is 0.091
Using Cohen's d and Cohen's guidelines for interpreting the effect size with the estimated Cohen's d, there is a

effect. Using r2 and the extension of Cohen's guidelines for interpreting the effect size using r2, there is a
treatment effect. (Hint:
When using Cohen's guidelines for interpreting the effect size, if the value lies between two categories, then specify the range covered by both
categories, for example, medium to large.)
Another one of the psychologist's findings is that a sample of 81 job seekers who received training on dressing for interviews scored an average of 8.1
