Can you see if I got the different validities right in this paragraph?

Question

The study only being done on UCCS college students is an external validity limitation because it cannot be compared to other college students or the general public. The participants being able to see the target before they were blindfolded is a statistical validity limitation because they had an idea of where the target was before they put the blindfold on to start throwing, which could give them a better idea of how hard or light to throw and could cause a more accurate throw. Although the participants were told they had to throw with their dominant or non-dominant hand, they were not told exactly how to throw it, so throwing it overhand or underhand is an internal validity limitation because one way could have been easier than the other where a participant could have had more hits or misses depending on the type of throw they performed. The floor could have been waxed on the day of the study, which is a construct validity limitation because it could cause the bean bag to slide out of the target easier, or if the study was conducted on more than one day, then the second day, the floor was not freshly waxed, so it did not affect the bean bags as much as the first day.

Answer 1

External Validity: Ability to generalize findings

Threat: small/convenient sample size

**Statistical Validity: The overarching type of validity- can we confirm our numbers are representing what we claim they do.(The 3 other kinds of validity mentioned fall under this umbrella)

Threat: participants are not blindfolded prior to seeing target, could create unwanted "aiming" or practice effect.

Correction: I don't think this would count as just Statistical Validity, I think there is definitely a better suited one in the six broken down categories. Statistical validity more speaks to the type of statistics used and the validity of the computed variables, not necessarily issues in the collection of data.

*****I would probably guess this is a form of Face Validity, ensuring the prepared instruments and measurements encapsulate all aspects of the variable.

Internal Validity: Confidence in cause-effect relationships by ruling out changes caused be extraneous factors.

Threat: Lack of specificity in throwing instructions could cause massive flux in numbers reported.

Construct Validity: how well a test measures the theoretical concept it was designed to evaluate

I think this might be a missed one as well, I believe construct has more to do with ensuring that all researchers and participants are fully aware of the constructs being tested or investigated.

I think this one would fall into the 'confound' category as opposed to Validity. Mainly because it is about the potential effects of the physical environment, which would be controlled for differently than validity.

External/Internal Validities look good to me, I think statistic could be better specified with a different validity check, and the final one might fall under something other than validity, if it is, then I would say its probably similar to Internal validity.

Hope this helps, let me know if I can clarify anything for you! Good luck :)
