Interpreting Values - AP Statistics

Interpret power…

Interpret power…

If Ha context is true at a specific value there is a power probability the significance test will correctly reject Ho.

Interpret standard error of the slope…

Interpret percentile…

percentile (%) of context are less than or equal to value.

Interpret correlation…

The linear association between x-context and y-context is weak/moderate/strong and positive/negative.

Interpret residual…

The actual y-value was residual above/below the predicted value when x-context = #.

Interpret y-intercept

The predicted y-context when x= 0 context is y-intercept.

Interpret slope…

The predicted y-context (increases/decreases) by slope for each additional x-context

Interpret standard deviation of residuals…

The actual y-context is typically about (s-value) away from the value predicted by the LSRL.

Interpret correlation of determination…

___% of the variation in y-value in context can be accounted for by the linear relationship with x-value in context

Interpret binomial mean…

After many, many trials the average # of success context of n is mu

Interpret binomial standard deviation…

The number of success context out of n typically varies by a standard deviation from the mean of mu.

Interpret standard deviation of sample proportion…

The sample proportion of success context typically varies by (standard deviation) from the true proportion of (___)
