Question

Can you please explain the Null Hypotheses to me in laymans terms? I understand it is a term used to say we do not believe something is not true?

Answer #1

In layman's term, the Null Hypothesis H0 is what we expect to happen before we run an experiment. The idea is that if the results do not reject the null hypothesis H0, then we are not finding anything new. The Null Hypothesis H0 is: "No change" or "No difference". For example, if our experiment is to find out whether a coin is biased or not, Null Hypothesis H0 is: The coin is not biased. i.e., p = 0.5.

If the experiment is to see if either boys or girls get good marks in the examination, the Null Hypothesis H0 is boys and girls both equally get good marks in the examination.

Can someone please explain to me why the medulla is smaller
rostral to the spinal cord? The explanation given to me via my
powerpoint & lecture is that majority of the tracts have
already decussated to the opposite side and then descend as the
lateral corticospinal tract. I feel silly, but I don't understand
how changing sides somehow makes you no longer a part of the
medulla. Can someone make this make sense because I feel like a
crazy person...
