This is where you can use sample data to answer research questions. For example, you might be interested in knowing if a new cancer drug is effective.

- Measures of Frequency: * Count, Percent, Frequency.
- Measures of Central Tendency. * Mean, Median, and Mode.

What is an example of descriptive statistics in healthcare?
It’s calculated by taking the square root of the sum of all numbers minus the mean (squared) and dividing by one less than the number of values. For example, in a data set of five systolic blood pressures of 125, 128, 142, 145, and 150, the mean would be 138, based on this calculation: (125+128+142+145+150)/5.
What are the four types of descriptive statistics?
Descriptive statistics describe or summarize a set of data. Measures of central tendency and measures of dispersion are the two types of descriptive statistics. The mean, median, and mode are three types of measures of central tendency.
What are the types of inferential statistics?

What are descriptive statistics used to describe?

What is the difference between descriptive and inferential?
The main difference between descriptive and inferential statistics is that descriptive statistics describe what the data show whereas with inferential statistics the goal is to reach conclusions that extend beyond the data in hand. Descriptive statistics are used to describe or summarize data in hand from a sample or a population.
