For the next $5$ questions, reference the above diagrams A through D $,$ dots represent scores of $12$ raters measuring height of one individual. $a=$ true $b=$ false

$52.$ Moving from left to right $($A to D$)$ error is increasing. $$

$53.$ Diagram C exhibits less reliability than diagram B $.$

$54.$ Pertaining to reliability, diagram D represents the following equation: $\frac{T}{T+E}$ where E is approaching zero $(0).$

$55.$ In diagram B$,$ reliability is high. $$

$56.$ Diagram B represents random error. $$
