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.

The idea of being at the "bottom" is one derived from the concept of social hierarchy. In a social hierarchy, certain groups in society are considered valuable and admired (at the top) while others are often ignored, abused, or rejected (at the bottom). In our society, this is usually related to the socio-economic position an individual has. Therefore, people at the "bottom" can often feel "invisible." They feel that the government, as well as social institutions, care little about their interests and needs.
Tammy Crabtree can be seen as an example of this. She is likely to feel invisible, as very few people care about her plight. She works far from her house, for a very low wage, and feels unable to improve her future.
