Q

Name an example sentence for expressing the correlation between two variables

A

The correlation between the variables X and Y is in-/significant because because the p-value (..) is (not) less than the chosen alpha value of 0,05

17
Q

Name the types of roles NFTs can play from companies perspective

A

1) NFTs as a product offering in their own right

2) NFTs as a means to achieve other goals (not related to product offerings

18
Q

Name examples for utilitarian benefits of NFTs as a product offering in their own right

A

1) NFTs are assets with future earning potential (e.g. 3LAUs album as an NFT)
2) • NFTs as a part of a bundling package to enhance the utilitarian aspects of NFTs (e.g., BAYC)

19
Q

BAYC

A

Bored Ape Yacht Club

20
Q

Name an example for hedonic benefits of NFTs as a product offering in their own right

A
  • Utilities associated with one-of-a-kind and exclusive products (e.g., NBA Top Shot)
  • An emotional selling proposition to sell NFTs (e.g., Budweiser, Gucci).
21
Q

Name examples for utilitarian benefits of NFTs as a means to achieve other goals (not related to product offerings)

A

• Higher instrumental benefits from products that are tracked and traced using NFTs (e.g., Icecap’s use of ERC721 token to track and trace diamonds)

22
Q

Name an example for hedonic benefits of NFTs as a means to achieve other goals (not related to product offerings)

A

• NFTs as a part of non-price promotions such as free giveaways, sweepstakes or other business initiatives such as CSR (e.g., Coca-Cola’s “rooftop” party on Decentraland, McDonald’s China gifting NFTs).

23

24
Q

Give more details on 3LAU’s use of NFTs

A
  • the DJ Justin David Blau has created the music platform Royal
  • artists can give their fans direct ownerships of their songs
  • fans can also receive royalties when the song gets popular
  • NFTs are offered at auctions via OpenSea
25
Give more details on the NBA's approach to use NFTs
- NBA Top Shot guarantees exclusive ownership of a digital asset and thus increases the utility associated with and social status that comes with the ownership of the asset - serial numbers are anothe huge indicator of value - customers/can be sure that they posses a valid product - sellling/exchange is made easily through the tamper-proof system
26
Give more information on Icecaps use of NFT
- ERC721 tokens to track diamonds - are an digital twin of the physical products - blockchain can store information on origin, owner history etc. - thus value of products might increase
27
Why can errors always be made?
Because we cannot make any statement about a sample with complete certainty, there is always the chance that an error will be made
28
When is a observation certain?
When a researcher makes the observation using a census, meaning that every unit (person or object) in a population is measured, then conclusions are certain
29
Long definition type 1 error
A Type I error occurs when a condition that is true in the population is rejected based on statistical observations
30
Long definition Type 2 error
A Type II error is the probability of failing to reject a false hypothesis. This incorrect decision is called beta (β).
31
How can errors in correlation be eliminated
-increase sample size (until full population is measured)
32
Why can Type 1 and 2 errors not simoultaneously eliminated?
-they are inversely related -lower significance level -> Type 2 higher significance level -> Type 1
