Answer: test statistic.
Step-by-step explanation:
The chi-square ( ) test is a non-parametric statistical test(also known as Goodness of fit test) which is used to determine if a distribution of observed frequencies differs from the expected frequencies.
Chi-square statistic uses either nominal (categorical) or ordinal level data.
Hence, When determining how well an observed set of frequencies fits an expected set of frequencies, the test statistic is test statistic.
Hey there!☺
When you are solving an equation, it is important to use <em>inverse</em> operations. You will need to use the <em>inverse</em> operations on both sides of the equation. And it is also important to isolate the variable. After you do that, you will need to reverse it up. The way to do all of this is using the <em>inverse</em>.
To solve an equation, you use <u>inverse</u> operations.
Hope this helps!
