${\displaystyle helloworld}$

Cronbach's ${\displaystyle \alpha }$ = .70

${\displaystyle {\hat {Y}}}$

${\displaystyle \eta \delta \Delta \lambda \Lambda }$

Sigma: ${\displaystyle \sigma }$

${\displaystyle {\sqrt {6}}4=8}$

${\displaystyle \eta ^{2}}$ and ${\displaystyle \eta _{p}^{2}}$

Can you even up the etas in the line above? I've asked about this here: Sizing symbols with subscripts.

One way seems to be to split the eta-squared and the subscript: ${\displaystyle \eta ^{2}}$ and ${\displaystyle \eta ^{2}}$${\displaystyle _{p}}$; even better maybe is ${\displaystyle \eta }$${\displaystyle _{p}^{2}}$.

Lambda: ${\displaystyle \lambda }$
