Do I need a statistical test for a 7 in my BIO IA?
Gingich posted a topic in Biology and ESSHi. I need some advice. My IA is about fungi so I have some data for growth over time for two conditions of one abiotic factor. The groups of the fungi in one of my two conditions (they took 2 months to grow bc of various reasons) have no growth of the fruiting body (thus no data). Thus it seems silly to use a statistical test since I know which condition was the *best ( growth was limited by lack of control of other variables) Any advice? Will this limit my chances of getting 7? I worked too much on this and now there is no data for 1 condition, just a load of qualitativ
Can I use an online calculator for biology IA?
Kevin Chan posted a topic in Biology and ESSIn my biology IA, I am using a statistical test called the one way ANOVA test. However, this test is overwhelmingly complicated that it would take ages for me to do all the calculations and showing them in the form of tables. Being in Y12 now I simply don't have that much time to dedicate hours into writing 8 pages of statistical calculations. So my question is can I use an online calculator? Can I simply reference the website in the report and say "due to the complexity of this test an online calculator was used." ? Will it influence my "personal engagement" criteria? Thank you very much
Statistical test for Biology IA HL
Kevin Chan posted a topic in Biology and ESSI am currently doing my Biology IA. I calculated the Mitotic index of six onion root tips for five different areas from top to bottom: root cap, mitotiz zone, elongation zone, and maturation zone. Now, I want to use a statistical test to show that there is a general significant difference between the five groups' mitotic index. I decided that an ANOVA (One-way analysis of variance) test will be approriate because it calculates differences between more than 2 groups of data. However, I don't know if IB will allow me to use this test because i heard IB may have restrictions on what kind of stati
Which statistical test for germination
Vicky Palami posted a topic in Biology and ESShey everyone. I´m almost done with my bio IA. It´s about the effect of coffee on the germination rate of bean seeds. I feel that it was a pretty simple experiment. I had 5 different containers. 10 seeds in each one, with different concentrations of coffee (I watered them with it), with one control group. The dependant variable was the days it took the seeds to germinate. The problem tthat I have is that I don´t know which statistical test I should use for the analysis. I did the ANOVA test but the result seemed...off. I don´t know if that was because ANOVA is not the right tool to use fo
