The effects of Typos and Grammos on the Housemate Scale.
Point estimates and 95% confidence intervals are taken from the model summarized in Table 4. Because traditional measures of effect size are not suitable to the statistical model used here, parameter estimates are used to indicate effects and confidence intervals provide an estimate of precision (see [23]).
Fig 2.
The effect of Agreeability on the Housemate scale, and the interaction between Grammos and Agreeability.
Participants were split into two groups at the median of Agreeability (3.78). The more agreeable group averaged a score of 4.21 on the agreeable scale of the BFI, while the less agreeable group averaged 3.21.
Fig 3.
The effect of the Extraversion trait on grammos (top) and typos (bottom).
Participants were divided into two groups at the Extraversion median of 3.125. The extraverted group averaged 3.80 on the Extraversion index of the BFI and the introverted group averaged 2.45.
Fig 4.
The interaction between Typos and Conscientiousness.
Participants were divided into two groups, using the Conscientiousness median of 4.00. The more conscientious group averaged 4.61 on the Conscientious subscale of the BFI and the less conscientious group averaged 3.30.
Fig 5.
The interaction between Typos and Openness.
Participants were divided into two groups, using the Openness median of 3.70. The more open group averaged 4.19 on the Openness scale of the BFI and the less open group averaged 3.15.
Fig 6.
Three-way interaction of Typos, Grammar Attitude, and Extraversion.
Introverted participants ratings of grammar attitude ranged from 3 to 7, while extraverts’ scores ranged from 5 to 7.
