What a finished MA 320 Unit 6 two-sample or paired comparison looks like
A design paragraph opens the document and it is written before any summary statistic appears. It quotes the sentence from the assignment that describes how the observations were obtained, and reasons from that wording to a conclusion about whether each value in one column has a partner in the other. Summaries for both groups follow, given side by side with counts, centers and spreads in the same units, and a picture that puts the two distributions on a common scale. The procedure is then named with the design cited as the reason for it, and the working is shown. Where the observations are paired, the differences are treated as the data and the summary reflects that. The closing reports the size of the difference in the units measured, before any statement about whether it is more than chance would produce.
How a MA 320 Unit 6 example is structured
The design is settled first because it determines the procedure completely, and no amount of care further down repairs a pairing that was missed at the top. The quoted sentence from the assignment is kept on the page so the reasoning can be audited by a reader who disagrees with the reading. Summaries come before the procedure to give a sense of scale, since a difference that matters and a difference nobody would notice can produce similar output and only the units tell them apart. The picture uses a common scale for both groups because two charts with different axes make any comparison unreliable by eye. Paired data are converted to differences before anything else is done with them, as that conversion is what the design licenses. The size of the difference is reported before the question of chance, because a result nobody can picture answers nothing.
The design settled before the summaries
How the observations were obtained is decided at the top, since that single question determines which procedure the rest of the document uses.
The describing sentence quoted and reasoned from
The assignment wording that fixes the design stays on the page so a reader can audit the reading it was given.
Both groups summarized on one scale
Counts, centers and spreads appear side by side in the same units, with a picture that does not distort the comparison.
Paired observations converted to differences
Where each value has a partner, the differences become the data, which is precisely what the matched design permits.
The size of the difference first
How far apart the two groups are, in the units measured, is reported before anything is said about chance.
Where marks go in MA 320 Unit 6
Choosing the wrong procedure for the design is the failure that defines this unit, and it costs the whole item rather than part of it. Two measurements on the same subjects analyzed as independent groups throws away the matching the study was built to exploit, and the reverse mistake invents a pairing that does not exist. Designs assumed rather than read, with no sentence explaining the choice, leave a marker unable to award the reasoning even when the procedure happens to be right. Differences reported as bare statistics, with no units and no sense of how large they are, answer nothing about the situation. Charts on separate scales make the comparison look like whatever the axes decided. Groups summarized with different measures cannot be set beside each other. Output pasted from software with no reading attached ends the document short.

MA 320 Unit 6 questions, answered
How do I tell whether my data are paired?
Ask whether each value in one column belongs to the same person, object or occasion as a value in the other. Before and after measurements on the same people are paired. Two groups of different people are not, even when the groups are the same size, and equal sample sizes are the coincidence that leads most drafts into treating them as matched.
Can I compare two groups from my own life for this?
Where the assignment lets you supply the situation, a comparison drawn from ordinary life works well: two routes to the same place, two months of the same household measurement, two batches of something you timed. Keep the people out of it or keep them anonymous, note how the observations were made, and be honest that the set is small. A modest dataset described accurately beats a large one you cannot account for.
The two groups have different sample sizes. Is something wrong?
Not in itself, and unequal sizes are ordinary in independent group comparisons. What they do rule out is pairing, since a matched design produces the same count on both sides by construction. Report both counts plainly, use the procedure your instructions name for unequal groups, and say nothing about balance unless the assignment asks, because an apology in the write-up reads as uncertainty about the design.
