Suppose That a Baseball Is Tossed Straight Up and That $h ( t ) = 128 t - 16 t ^ { 2 } \mathrm { ft }$

question 183

Short Answer

Suppose that a baseball is tossed straight up and that its height as a function of time (in seconds) is given by the formula $h ( t ) = 128 t - 16 t ^ { 2 } \mathrm { ft }$ . What is the maximum height of the ball?

Definitions:

Error Variance

Random variability in a set of scores that is not the result of the independent variable. Statistically, the variability of each score from its group mean.

Between-Groups Variance

captures the differences in means across different groups in an experiment, reflecting how much group members vary from each other overall.

Within-Group Variance

The variation of observations within a single group or category, measuring how much individual scores differ from the mean of that group.

Statistical Significance

Refers to the likelihood that a result or relationship is caused by something other than mere random chance.
