short answer: There are a few words that scientists do not use when publishing their findings. (In lecture, I referred to these terms as "dirty words"). What are some of these words? Why are they not found in credible scientific publications? (Ch1 #17)

Words like proved, right, wrong and true are not used in credible scientific publications.

Phrases like 'definitely', 'always', and 'absolutely' are common in research articles.

Terms such as 'certain', 'likely', and 'may' are avoided in scientific writing.

Words like 'confirm', 'often', and 'sometimes' are used in scientific publications.

3. The research has an ‘n’ value of 2

1.The researcher rejected their hypothesis

2.The researcher found no significant difference between their two test groups

Observer independently verifies or calibrates sensors before deployment

5th law data management

document and describe their methods/ calibration

Data integrity and accuracy management

6th law data management

should qualify level of calibration accuracy / expected error

7th law data management

Data storage is irrelevant to data management.

Data management only concerns hardware resources.

6th law data management

Observers should qualify level of calibration accuracy / expected error

5th law data management

need to document and describe their methods/ calibration

Data storage is irrelevant to data management.

Data management only concerns data retrieval.

Data management focuses solely on data visualization.

4th law data management

1st law of data management

Real time observation must be accompanied by quality descriptor

Data can be inconsistent and still valid.

Data must be outdated and unreliable.

Data should be kept secret and inaccessible.

What does it mean when data are interpreted as having “Significant difference” vs “No significant difference”?

“Significant difference”= significance using a standard 95% confidence

“No significant difference”= if the analysis shows that differences would be expected to occur by chance more than one out of twenty times

“Significant difference”= if the analysis shows that differences would be expected to occur by chance more than one out of twenty times

“No significant difference”= significance using a standard 95% confidence

what is “Significant difference”

significance using a standard 95% confidence

A significant difference refers to a minor change in data.

A significant difference is a term used in everyday conversation.

A significant difference means there is no difference between groups.

what is “No significant difference”

if the analysis shows that differences would be expected to occur by chance more than one out of twenty times

A method for determining statistical significance.

A term used in qualitative research.

A hypothesis that suggests a strong correlation.

What is bias? How do we manage it?

Bias is a tendency to favor one perspective over others, and it can be managed through awareness, diversity, structured processes, and feedback.

Bias can only be eliminated by ignoring it.

Bias is a scientific term with no social implications.

any factor in an experiment that can be changed or tested.

A variable is a function that performs calculations.

A variable is a type of data structure that holds multiple values.

A variable is a constant value that cannot change.

what are the major components of the scientific method?

observation, question, hypothesis, experiment, data analysis, and conclusion

theory, observation, conclusion, prediction

hypothesis, conclusion, data collection, review

experiment, analysis, review, publication

Testable means can be proven or disproven through empirical evidence.

Testable refers to something that is unchangeable.

Testable means it cannot be evaluated.

Testable is synonymous with being irrelevant.
