if an independent-measures study uses n = 15 participants in each group to compare two treatment conditions. then 28 is the df value for the t statistic for this study.
The t-statistic, which is used in statistics, measures how far a parameter's estimated value deviates from its hypothesised value relative to its standard error. Through the Student's t-test, it is utilised in hypothesis testing. In a t-test, the t-statistic is used to decide whether to accept or reject the null hypothesis. The t-statistic is used when the sample size is small or the population standard deviation is unknown. It is quite similar to the z-score in other respects. Once the standard deviation is unknown, the t-statistic is in use, for one, to approximate the population mean from a sampling distribution of sample statistics.

i used to have this when i was 9. here's the google definition:
"Children are especially prone to separation anxiety during times of stress.
Separation anxiety differs from normal clinginess. Children with the disorder can't think about anything but the present fear of separation. They may have nightmares or regular physical complaints. They may be reluctant to go to school or other places.
Treatment includes talk therapy and possibly anti-anxiety medication."
<em><u>Thoreau</u></em>
Emphasizing and creating idealities that one's ideas and perceptions are significant and should be given importance is one quality that can blind one's perception to understand and entertain other ideas, especially with others ideas. Hence Sojourner shared this common attitude with <span><u>Thoreau</u></span>
