What is Statistics in biology?
Abstract: Statistics represents that body of methods by which characteristics of a population are inferred through observations made in a representative sample from that population. Since scientists rarely observe entire populations, sampling and statistical inference are essential.
What are the two types of Statistics?
Statistics is a branch of mathematics used to summarize, analyze, and interpret a group of numbers or observations. We begin by introducing two general types of statistics: •Descriptive statistics: statistics that summarize observations. •Inferential statistics: statistics used to interpret the meaning of descriptive statistics.
How do researchers interpret or infer the meaning of data?
As a result, researchers use procedures that allow them to interpret or infer the meaning of data. These procedures are called inferential statistics. Inferential statistics are procedures used that allow researchers to infer or generalize observations made with samples to the larger population from which they were selected.
