Step1
Solution:
Descriptive statistics are used for summarizing and organizing data to understand data easily.
Step 2
There are two categories of descriptive statistics used for quantitative data that are given as follows:
- Measures of central tendency: It includes Mean, Median.
- Measures of Dispersion: It includes Standard deviation, Mean deviation, Variance, Range, Percentile, Quartiles and Interquartile range.
If the distribution of data is skewed, it is better to use median from central tendency measures and interquartile range from dispersion measures. As they both are measured using middle 50% of the data, they are resistant to extreme observations.

True or False
1.The goal of descriptive statistics is to simplify, summarize, and organize data.
2.A summary value, usually numerical, that describes a sample is called a parameter.
3.A researcher records the average age for a group of 25 preschool children selected to participate in a research study. The average age is an example of a statistic.
4.The median is the most commonly used measure of central tendency.
5.The mode is the best way to measure central tendency for data from a nominal scale of measurement.
6.A distribution of scores and a mean of 55 and a standard deviation of 4. The variance for this distribution is 16.
7.In a distribution with a mean of M = 36 and a standard deviation of SD = 8, a score of 40 would be considered an extreme value.
8.In a distribution with a mean of M = 76 and a standard deviation of SD = 7, a score of 91 would be considered an extreme value.
9.A negative correlation means that as the X values decrease, the Y values also tend to decrease.
10.The goal of a hypothesis test is to demonstrate that the patterns observed in the sample data represent real patterns in the population and are not simply due to chance or sampling error.
