## T-Statistic

The t-statistic is a ratio that measures the size of the difference relative to the variation in the sample data. It is used in hypothesis testing to determine if a coefficient in a regression model or a mean difference is significantly different from zero.

In quantitative trading, a high t-statistic indicates that the observed effect is likely not due to random chance. It is a key metric for evaluating the significance of trading signals.

When developing automated strategies, traders look for high t-statistics to confirm that their variables have a genuine impact on price action. It helps in refining models and removing features that do not contribute to predictive accuracy.

The t-statistic is a vital component of the statistical toolkit for financial researchers.
