so weber laws includes, if a price that is relatively cheap to begin with and the price increase people will notice but if its a price of a luxury car increase people wont notice as luxury cars are supposedly already expensive
I suppose so!
weird flex but ok lol
Hi,
I am fairly new to this. But I think we need to first define what luxury here means? Is it just the brand name or the facilities provided as luxury.
I think assumptions in our head plays a vital role here. As rightly said by you, a luxurious car (Based on the brand) tends to be expensive already. So, a small increase in its price won't be noticeable.
whereas, a regular car say of 39K (currently under a bracket of 35-40K) when increased by 1.5K reaches a bracket of 40-45K is very noticeable.
as far as I have read Webers law is very subjective. So, while we make a bigger purchase we tend to diminish the add onn amounts
Luxury car: initially 90K :: increased by 3K :: now 93K
Regular car: 35K :: increased by 3K :: now 36K
A packet of chips: 1 dollar: increased by 3 dollars: now 4 dollars | (pls ignore thse exaguration)
so, when the initial price is low: the increase by a certain amount is quite noticeable (in a packet of chips)
where, when the price is already very high, the increase in not so noticeable (in the Luxury car)
So, I agree with you.
@@vedantkhare953 a 1993 honda prelude ( the car I drive ) is considered a luxury car in japan and is taxed as a luxury car by the government of japan, however someone in USA would consider it a tin can regardless of its features offered. What is luxury is different to the consumer and many variables would decide it. To some having a car period is luxury compared to walking, taking a bus, or travel by horse. What is luxury? Who defines luxury? Mercedes and BMW interiors fall apart very easily, and require very strict service costly on strict intervals with strict costly service consumables followed by longer and more costly labor times, yet deliver less reliability and provide the driver with less road time unless a price is paid. I do not consider those "luxury" as they constantly and forcefully require the driver to spend $$$$ on service and repair to maintain the vehicles basic ability which is transportation. Transportation by vehicle alone is a luxury compared to using your own two legs. A Toyota Tercel can deliver near endless transportation with little to no service, at an extremely small cost. I consider that luxury, a vehicle that works and always works, with the little cost.
I am fighting it over one month and u just made it so easy in just 9 minutes thank u so much💜
and this law explains how in cognitive psychology, pitch change is largely perceived according to the differences/changes in ratio; hence minor changes are not usually detected by humans. thanks Weber!
you explain it better than anyone else on CZcams. gee that make it so complicated
wow! THANK YOU!! I was so confused on what all this really meant
This has never been so easy for me to understand. Thankyou so much.
fantastic job! thank you so much!!!
it's amazing explanation..
perfect! thank you
Well Explained! Good Job!
amazing explaination
This is a beautiful equation; a representation of the poetry of mathematics.
Thank you so much! Very simple and easy to follow. Almost too easy that I thought it wouldn't give me the correct answer. I thought this was rocket science at first! aha
THANK YOU SO MUCH!!
thank you for saving my life
That was so easy.. 🔥
THANK YOU SO MUCH
who else is reading the KA 300 page doc (or the 86 page one even)? lol
Well explained
Thank you so much ❤️🥺
Thank youuu
Thank u sooo much ❤️
This is really helpful thank you. Do you happen to know how to calculate the limit of frequency discrimination for two pitches (the point at which two different frequencies are heard instead of beating) for complex and simple sound waves like a sine wave and also the point at which beating turns into a more unpleasant coarseness before it reaches the limit of discrimination?
The examples given are just so realistic
for whoever is still confused about this concept, here's an example that helped me:
Imagine you have a bag of candies, and you want to notice if someone adds more candies to it. Weber's Law says that the amount you need to add for you to notice the change depends on how many candies you already have.
If you have just a few candies, adding one more is a big deal, and you'll notice it right away. But if you have a lot of candies, you might need to add more for you to notice a change. So, Weber's Law helps you figure out when things are different, depending on how much you already have.
thank you so much for the example!
I like this guy better than khan
Very nice but please improve the voice quality
I think I love you.

I've only just come across Weber's law but surely the linear graph couldn't stay as a constant linear progression. If I could bench press 100kg at the gym for my 1 rep max but failed to bench press 102.5kg, then that 2.5% increase would have much more impact than adding 2.5kg to a 50kg bench press. Does Weber's law only work on the lower ends of what our body's are capable of?
Hi Ryan,
I too have same doubt.
But I think we need to first take initial reading. What I mean is that did you try
> 1st reading
Weight= 10 KG
Delta Weight= 12.5 KG
Did you find any 'JND' here?
> 2nd reading
Weight= 20 KG
Delta weight= 22.5 Kg
any JND= ?
> 3rd reading
Weight= 50 KG
Delta Weight= 52.5 KGs
JND=?
Maybe then we can look for weight= 100 and Delta weight=102.5.
we might need initial Limen reading.
I could be very wrong but just an assumption
Hi,
I = 100 kg
Change= 102.5 kg
∆i= 2.5
∆I/I =k
2.5/100= 0.025 =k
I= 50
∆I= ?
k= 0.025
∆I = k × I = 50× 0.025 = 1.25
∆I = 1.25 kg
JND= 1.25 kg
Which means that at 50kgs
50+1.25 kg = 51.25 kg
So, between 50 and 51.25 no difference is noticed
At exalty 51.25 kgs we will notice difference
Actually Yes !!!
The law doesnt work at lower end...AND at the Higher end..
I think that was the criticism of this theory actually !
bro sounds like kermit
You should make examples clearer to form. Weber's law is for 2% increases
Fechner law???

I feel like this video isn't up to par with the rest of the KA videos
