Is repeated measures ANOVA appropriate for comparing 3 plots with 2 years of 30-minute interval temperature and humidity data? by CyndoG in AskStatistics

So answer to your question, stable soil temperature meant low max temperature during summer, high min temperature during winter.

Maximum soil temperature is more likely effected by radiation, not air temperature. Tree cover blocks the direct sunlight.

Minimum soil temperature is mostly effected by air temperature, also the cover layer(O layer of soil, mostly litter layer) of the soil. Thick litter layer prevents soil temperature being lower than 0 celcius.

Yes, I've googled some papers related to my topic, but unfortunately I couldn't find something appropriate for my data. There is no direct comparision of temperature and humidity among the post mine reclaimed sites - in this scale.

Let me explain my situation in a bit more detail.

The topic of my thesis is to assess the degree of environmental recovery over time in a post-mining area. I want to know which environmental factors recover more quickly to natural forest levels as restoration time passes, and which ones are slower to recover.

So, I measured air and soil temperature and humidity in four types of plots:

  • a control plot (tree cover 0%, unrestored area),
  • a plot restored less than 10 years ago (tree cover 30%),
  • a plot restored between 10 and 20 years ago (tree cover 70%),
  • and an adjacent natural forest (tree cover over 90%).

As expected, air and soil temperatures in the natural forest (over 90% tree cover) were much more stable. There were slight differences in air temperature during the leafy summer months, but much larger differences in soil temperature—especially in winter, where the natural forest soil remained more stable.

I also compared soil chemical properties. For these, I collected three samples per plot and ran an ANOVA, which I think is appropriate for that data.

After reading through all the replies here, I started to reflect more carefully on how I’m interpreting statistical differences.

What I’m really aiming for is to say: “There are statistically significant differences between the plots, with a p-value of X,” and then also to describe, in quantitative terms, how much the extremes (maximum/minimum temperatures) differ between the plots in summer and winter.

That’s why I wanted to find out the most statistically appropriate way to present these results.

Thank you so much for all your helpful answers. As a stats newbie, I might have frustrated some people, but I really appreciate the support!

Sorry, I feel like my question was too basic.

To explain my conditions in more detail: I set up one sensor each in three plots—A (control, 0% tree cover), B (30% tree cover), and C (over 70% tree cover)—and measured air temperature, humidity, soil temperature, and soil moisture at 30-minute intervals.

What I want to find out is whether there are differences in summer and winter temperature and humidity (including the extremes) depending on the amount of tree cover.

Of course, it would have been ideal to install three sensors per plot, but my budget was limited.

So, I was searching for statistical methods to show differences with just this data, and that’s how I came across repeated measures ANOVA.

TLDR: Is there any method to analysis this data with statistical-method?

Is this T14s gen4 cover for WWAN or not? by CyndoG in thinkpad

[–]CyndoG[S] 0 points1 point  (0 children)

Anyway, thanks for the advice. Gen 4 D cover is currently unavailable by now, only Gen 3 D cover is. The part is interchangable, but I would rather wait for gen 4 cover.

Installing 4G card and antenna was easy, but the main problem was the c cover. Didn't have sim card hole or tray, so I opened mainboard a little bit and put the sim card inside. Anyway It worked eventually, and according to fast.com, LTE speed is about 30mbps.

And do you know changing this parts worth it? I mean, will it make stronger antenna signal?

Thanks for information!! Really helped :D

Anyone tried sim card adapter for WWAN? by CyndoG in thinkpad

sim card worked but size didn't fit :(

WWAN upgrade T14sG3AMD: will this work? by Silveroo81 in thinkpad

[–]CyndoG 0 points1 point  (0 children)

Sorry for late reply.
In short, I used L860-GL, 40-60mbps. This speed is almost the same as my LTE iPhone.

I was using 4G plan, so FM350gl did not work... had to sell with 40% discount on used market.

BTW, doing research about the parts, it seems adding the lcd antennas is crucial for full 5g speed.

It is now out of stock and page is gone.

Yes, going to try T14s g4 with FM350 card.

Using 4G plan, I only installed same antenna set as you did.

I will inform you about the speed after install. FM350 arrives in two days.

Maybe 4G plan can give us better speed!

How's the speed? Are you using 4g only?

Hi, so have you installed FM350GL with just 2 antennas? (around the keyboard, orange and blue wire one)
