Here is a famous rule of thumb for assessing computed t values: We can instantly treat an associated regression coefficient as statistically significant at the 95 percent level of confidence whenever: A the magnitude of a computed t value is negative B the absolute magnitude of a computed t value exceeds 1 C) the absolute magnitude of a computed t value exceeds 2 the magnitude of a computed t value is positive The total deviation is the: Treatment Deviation + Error Deviation Treatment Deviation squared Treatment Deviation + Unexpected Deviation + Error Deviation Treatment Deviation Here is a famous rule of thumb for assessing computed t values: We can instantly treat an associated regression coefficient as statistically significant at the 95 percent level of confidence whenever: A the magnitude of a computed t value is negative B the absolute magnitude of a computed t value exceeds 1 C) the absolute magnitude of a computed t value exceeds 2 the magnitude of a computed t value is positive The total deviation is the: Treatment Deviation + Error Deviation Treatment Deviation squared Treatment Deviation + Unexpected Deviation + Error Deviation Treatment Deviation
