Mary conducts research examining the efficacy of treatment of elderly persons in nursing facilities in her home state. in order for her to use this research to influence larger political policies regarding the care of the elderly on a state and federal level, she will have to generalize her findings to the larger population of elderly nursing home residents. what sort of statistics should she use to accomplish this goal?

The answer is "inferential statistics".

Inferential statistics utilize a random example of information taken from a population to depict and make deductions about the populace. Inferential statistics are significant when examination of every individual from a whole populace isn't advantageous or conceivable. For instance, to gauge the distance across of each nail that is fabricated in a plant is illogical. You can quantify the measurements of a delegate random sample of nails. You can utilize the data from the example to make speculations about the widths of the greater part of the nails.
