Explanation

Cohen's kappa measures inter-rater reliability for categorical data while correcting for agreement occurring purely by chance.

Additional Information:

Inter-Rater Reliability: Quantifies the degree of concordance between independent evaluators on categorical outcomes.

Chance Correction: Provides a more conservative and accurate measure of rating consistency than simple percentage agreement.

Explanation

To find the Arithmetic Mean (Average):

Add the numbers: 10 + 20 + 30 + 40 + 50 = 150

Count the numbers: 5

Divide the sum by the count: 150/5 = 30

Explanation

Mean of 6 observations = 42

Total of 6 = 42 x 6 = 252

Sum of 5 given observations:

35 + 39 + 41 + 46 + 50 = 211

Sixth observation = 252 - 211 = 41

Explanation

Total possible outcomes for two dice is 36.

There are 6 ways to get a sum of 7 which are (1,6), (2,5), (3,4), (4,3), (5,2), (6,1).

So probability is 6/36 which simplifies to 1/6.

Explanation

When two dice are rolled, there are 36 possible outcomes

The outcomes that result in a sum of 7 are (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1), which are 6 in total.

So, the probability of getting a sum of 7 is 6/36 = 1/6.
