Evaluate Knowledge of Cognitive Skill based on HCI System and Analyze the Reliability Factor using Mathematical Method

摘要

An aim of this research is to analyze the reliability factor between logical reasoning, numerical ability and perceptual speed which relates to the qualification of mother and father and hours spend to daily variables based on Karl Pearson Correlation Coefficient. These analyses help to students’ self development and level of confidence in their ability reason and can justify their thinking will increase and stimulate the skill positively. Based on framing the hypothesis, an analysis can be carried out by Karl Pearson’s correlation coefficient method and differential analysis (T-test) to find out by significant difference between the variable.
