Find the following based on this set of scores:
$19,18,14,19,10$19,18,14,19,10
Find the mean.
Complete the following table.
Score($x$x) | $(x-$(x−mean$)$) | $(x-$(x−mean$)^2$)2 |
---|---|---|
$19$19 | $\editable{}$ | $\editable{}$ |
$18$18 | $\editable{}$ | $\editable{}$ |
$14$14 | $\editable{}$ | $\editable{}$ |
$19$19 | $\editable{}$ | $\editable{}$ |
$10$10 | $\editable{}$ | $\editable{}$ |
