Some more embodiment analyses

Here are some more (explorative) analyses from the embodiment data used the Embodiment in character-based video games.

I collected also workload data using raw Nasa TLX when gathering data for EFA and CFA, but then I did not use workload data in analyses. My assumption was that workload would correlate with the embodiment, but did not look at this.

Confidence intervals & credible intervals

This is a note for me.

Confidence intervals: “Are the observed data x reasonable given the hypothesised values of θ?” == P(θ| x)

Those are related as “P(θ| x) = P(θ)P(x| θ)”

Credible intervals are part of Bayesian approach.
