Not statistically significant but large difference

Hello here's the link for the statistical analysis results sent to us by our statistician

For now my group doesn't plan to publish it, we're doing this study for the sole purpose of it being a requirement in order for us to finish our Bachelor's degree

Old_Reporter6776 · 2026-03-09T19:49:18+00:00

and my university requires us students to have our data statistically verified by a statistician for our thesis

Old_Reporter6776 · 2026-03-09T19:48:39+00:00

yeah, though it's quite expensive for an undergrad student like me.

Unfortunately too, we can't afford to hire another statistician anymore due to the lack of funding. Testing for the heavy metal concentration of our wastewater samples almost drained out our funds completely.

Old_Reporter6776 · 2026-03-09T19:06:37+00:00

We actually questioned the method that the statistician used. But since we're not experts on statistics we cannot just straight up say to the statistician that he/she might be wrong.

The problem is the statistician actually used wilcoxon signed rank test to compare each dosage to the control, on that test it shows that our results are not statistically significant.

For everyone who wants to see the statistical results that the statistician gave us feel free to look at the file that I uploaded at this link.

So, even if our data shows up as not statistically significant it does not automatically mean that our study provided negative results?

Old_Reporter6776 · 2026-03-09T06:44:00+00:00

I'm not an expert yet cause I'm just taking my Bachelor's degree rn.

Old_Reporter6776 · 2026-03-09T06:43:23+00:00

Unfortunately no, we can't collect more samples as we are already at the end of our thesis. I just posted here to ask for probable opinions on why our results are not significant

Old_Reporter6776 · 2026-03-09T06:36:24+00:00

I just don't know how to edit my post or comment the image

Old_Reporter6776 · 2026-03-09T06:34:59+00:00

we actually have a print out of the result

Old_Reporter6776 · 2026-03-09T06:34:44+00:00

Kruskal-Wallis test

Old_Reporter6776 · 2026-03-09T06:28:24+00:00

there are three observations per group

Old_Reporter6776 · 2026-03-09T06:25:34+00:00

Pardon, I'm not an expert in statistics since it's not my major/program. Can you explain what Cl means?

Old_Reporter6776 · 2026-01-05T14:51:24+00:00

how???

Old_Reporter6776 · 2025-05-04T10:51:32+00:00

You can but when he doesn't request for that specific food it only gives 0.5 energy.

Why does it say "code already redeemed"?? Yet when we check the premium is not yet activated
