To calculate the coefficient of variation (CV) for each sample, we'll first need to calculate the mean and standard deviation of each sample. Systolic Measurements: Calculate the mean: μ = (120 + 130 + 159 + 94 + 156 + 122 + 117 + 136 + 126 + 122) / 10 μ = 1232 / 10 μ = 123.2 Calculate the variance: σ² = Σ(xi - μ)² / (n - 1) where xi are individual measurements and n is the number of measurements. Calculating variance: σ² = [(120-123.2)² + (130-123.2)² + ... + (122-123.2)²] / 9 σ² ≈ 341.56 Calculate the standard deviation: σ = √σ² σ ≈ √341.56 σ ≈ 18.48 Calculate the coefficient of variation (CV): CV = (σ / μ) × 100 CV = (18.48 / 123.2) × 100 CV ≈ 15.0% Diastolic Measurements: Calculate the mean: μ = (78 + 77 + 72 + 50 + 92 + 87 + 56 + 66 + 72 + 84) / 10 μ = 764 / 10 μ = 76.4 Calculate the variance: σ² = Σ(xi - μ)² / (n - 1) Calculating variance: σ² = [(78-76.4)² + (77-76.4)² + ... + (84-76.4)²] / 9 σ² ≈ 171.78 Calculate the standard deviation: σ = √σ² σ ≈ √171.78 σ ≈ 13.11 Calculate the coefficient of variation (CV): CV = (σ / μ) × 100 CV = (13.11 / 76.4) × 100 CV ≈ 17.2% Comparison: The coefficient of variation for systolic measurements is approximately 15.0%, while for diastolic measurements, it's approximately 17.2%. Although the systolic measurements have a larger standard deviation (18.48 vs 13.11), the diastolic measurements have a slightly higher coefficient of variation. This indicates that the diastolic measurements have relatively more variation compared to their mean value. In general, a higher CV indicates greater relative variability within the dataset.
thanks！ I want ask a question that is is there any apps can practice linear algebra .I want found some app that can practice math only with phone that I can do it everywhere even if I was in bed
I am not good at math and use Gauth not just for the answer, but to explain the steps to get to the answer. I just looked up some linear algebra questions, print screen on my phone, and uploaded to Gauth. It gave the answers and explanations. Try it!
Does anyone use their Brain anymore to learn rather than rely on AI? I stopped using AI to write letters because who the hell wants a letter from a stupid uncaring robot? Sad this society thinks it's not doing anything wrong. Now I see why they want a leader who represents them the same way and who does Nothing wrong.
Photo math always fails, Gauth math fails often but not every time, I use it for statistics and it gave incorrect answers often. I haven’t tried chatgbt yet but all the other were really bad.
and now gauth has a function to switch between 4 AI's like gauth, the pro version, chat gpt and gemini, definitely the best one is gauth.
To calculate the coefficient of variation (CV) for each sample, we'll first need to calculate the mean and standard deviation of each sample.
Systolic Measurements:
Calculate the mean:
μ = (120 + 130 + 159 + 94 + 156 + 122 + 117 + 136 + 126 + 122) / 10
μ = 1232 / 10
μ = 123.2
Calculate the variance:
σ² = Σ(xi - μ)² / (n - 1)
where xi are individual measurements and n is the number of measurements.
Calculating variance:
σ² = [(120-123.2)² + (130-123.2)² + ... + (122-123.2)²] / 9
σ² ≈ 341.56
Calculate the standard deviation:
σ = √σ²
σ ≈ √341.56
σ ≈ 18.48
Calculate the coefficient of variation (CV):
CV = (σ / μ) × 100
CV = (18.48 / 123.2) × 100
CV ≈ 15.0%
Diastolic Measurements:
Calculate the mean:
μ = (78 + 77 + 72 + 50 + 92 + 87 + 56 + 66 + 72 + 84) / 10
μ = 764 / 10
μ = 76.4
Calculate the variance:
σ² = Σ(xi - μ)² / (n - 1)
Calculating variance:
σ² = [(78-76.4)² + (77-76.4)² + ... + (84-76.4)²] / 9
σ² ≈ 171.78
Calculate the standard deviation:
σ = √σ²
σ ≈ √171.78
σ ≈ 13.11
Calculate the coefficient of variation (CV):
CV = (σ / μ) × 100
CV = (13.11 / 76.4) × 100
CV ≈ 17.2%
Comparison:
The coefficient of variation for systolic measurements is approximately 15.0%, while for diastolic measurements, it's approximately 17.2%.
Although the systolic measurements have a larger standard deviation (18.48 vs 13.11), the diastolic measurements have a slightly higher coefficient of variation. This indicates that the diastolic measurements have relatively more variation compared to their mean value.

2 days ago I gave chat gpt a L.C.M math to solve but it gave me wrong answer continuously.
Prob chat gpt 3.5, gpt 4 is way better
@@pelagielutondo1987 now we got 4o. I'm getting a degree just thanks to chatgpt (I dont need the knowledge, I just need the scammy piece of paper)
@@pelagielutondo1987 both are shit for math, 4 is just less shitter
For maths contact your teachers/seniors, it's the best way
Gauthmath also gives wrong answers sometimes time.
What is the best way to enter the math question on chatgpt?
You can type it.
Oh that was a surprising one@@chrisrgutierrez
Voice typing also works and its fast too
I always type into mathway first then copy it from there onto GPT
Now you can upload images
To be fair, gauthmath uses chatgpt in the background
no it doesn’t it uses bing ai
thanks！ I want ask a question that is is there any apps can practice linear algebra .I want found some app that can practice math only with phone that I can do it everywhere even if I was in bed
did you find any apps for linear algebra ?? I also want an app for that.

Statistics is the more important of all of them
I feel like for the 4th question mathway is correct cause that’s how you would get the answer if imaginary numbers are allowed
Can Gauthmath do Geometry questions effectively?
No!!!! It gives wrong answers every time!!!
Give them Time independent Schrodinger equation
How does chatgpt not answer question 4?? Itlooks ez
Chat GPT 3 smh... I wish they use 4 this video
@@royvstheworld9681gpt 4 is also trash for math
Im looking for a. App that answers a math question, but also shows the steps and solutions, im stuck on an question
gauth
I would like to know on Gauthmath what are tickets? And if I choose the paid version do I get unlimited answers? Thank you :)
All I ever get r wrong answers. Over & over.
Bro, how's the app?
Nice video is Wolfram alpha better than ChatGPT/Gauthmath?
Should have used gpt 4
Gpt4 is still trash for math

0:55 NegativeNumber^(4/3) surely is undefined.
Interesting to compare these 4, but there u surely lost me.

Try Gemini also. It is good with math.
Can gemini solve linear algebra ??
@@aglosdoum1626 I couldn't say about linear algebra. It is surprisingly good with word problems that you would encounter in Algebra II, however.
So only ChatGPT can solve statistic problems?
Gauth AI can now solve statistic problems
Which one is the best?
@@ldp6481 gauth
51 subscribers. Drops chat get in the equation. 41k views and counting. You do the math ;)
Thank you so very very much 🙏😇
Bro, how's the app?
Love from BHARAT
Good work lady keep it up, 💪🏼
I need for graph
Thanks for the gauth math is better
How to use this app?? Huhu . I dnt knw how ..
Plz make more videos
Chatgpt cannot give correct answer of 123123÷13
Bravo
You look cute lady with a great voice 😍✌🏻✨
gauthmath be scammin i think this video fake
I use gauth, it's better than you think
@@JerkM8YTno it is wrong

Yes chat got is more accurate
@@SakuraArtCraft then how do you explain me passing my college cal exam lmao
