Question

Arun is taking a psychology class, which at the moment is focusing on the scientific method. Arun was somewhat surprised to learn that once data have been collected, two basic types of analyses can be used:_________.

Answer 1

descriptive and inferential statistics

Step-by-step explanation:

Descriptive statistics are numbers that are used to summarize and describe data.

Inferential statistics on the other hand makes inferences about populations using data drawn from the population. Instead of using the entire population to gather the data, the statistician will collect a sample or samples from the millions of residents and make inferences about the entire population using the sample.

The major difference between descriptive and inferential statistics is that descriptive statistics uses the data to provide descriptions of the population, either through numerical calculations or graphs or tables while inferential statistics makes inferences and predictions about a population based on a sample of data taken from the population in question.
