Null hypothesis testing (4 steps) a statistical method that uses data from a sample to evaulate a hypothesis about a population. 1. State the hypotheses.

A fact is an observation that has been confirmed and is accepted as true.The difference between hypotheses and theory is that the hypotheses is given based solely on observations.It is more of a guess. Based on what we see, we think is possible and could happen, we form a hypotheses.

In scientific experiments, a hypothesis proposes and examines the relationship between an independent variable and a dependent variable. The effect on the dependent variable (the idea being tested) depends on or is determined by what happens when you change the independent variable (the factor being changed). Whats a nulll hypothesis.

A) a prediction about something that has not yet been observed B) an instrument that is used to examine environmental conditions C) the design of an experiment that can be used in scientific inquiry D) a testable proposition that explains an observed phenomenon or answers a question E) a proven scientific fact

we formulate two hypotheses. • Research hypothesis (H1) • Null hypothesis (H0) Research hypothesis (H1) A substantive hypothesis expressed in terms of population parameters. • We use our sample statistics to make statements about population parameters. • H1 states that there is a difference between the two groups. Test statistic. The formula used to find the observed value, OV, of the test statistic, where the OV is a quantity that is used to make a decision in a test of hypothesis. The OV tells us where on the distribution curve the point falls. Level of Significance - alpha. It’s real. It’s gritty. It’s honest.
