What is the aim or focus to investigate when starting an experiment?

prediction

prediction with evidence

the observation

the question

What is the first step in writing a hypothesis?

identify the key variables

write the hypothesis

operationalize the variables

decide on a direction for your prediction

What option best describes the defintion of a theory?

prediction with evidence

prediction without evidence

an experiment

an analysis

What option best describes the purpose of a theory?

summarizes and simplifies a collection of information

describe behavior

identify the relationship

What is a benefit of operationalizing variables?

being able to replicate a study so others can perform the experiment and gather further evidence to support your theory

There is no benefit to operationalizing variables

A carefully worded statement of the exact steps

What are the two types of alternative hypotheses?

directional hypothesis

nondirectional hypothesis

null hypothesis

What does hindsight bias mean?

after learning an outcome, you then say you knew the result was going to happen all along

overconfidence

commonsense

What is a synaptic gap or cleft?

The small gap between the axon of a presynaptic neuron and the dendrites of a postsynaptic neuron

the electrical impulse sent along an axn when the dendrites of a neuron are excited

a specialized chemical messenger 

What are the four neurotransmitters that EDSO stands for?

Why is an operational definition necessary when reportinng research findings?

An operational defintion provides more context and includes many examples of the content described

An operational definition is easier to translate into multiple languages than a dictionary defintion 

An operational defintion uses more scientific language than a dictionary defintion

An operational definition allows others to replicate the study

An operational definition is not necessary since a dictionary definition will work as well for replication
