In order to test a non directional hypothesis, a researcher would use what kind of test? ○ one-tailed ○ alternative ○ critical ○ two-tailed

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.

Sorry i don’t know what to do
