Answer:
Cohen's D
Step-by-step explanation:
Cohen's D is a statistic that measures effect size. It shows standardised difference between 2 means.
Effect size is defined as how large the effect of a something is or its magnitude.
Cohen's D works effectively when the sample is >50 (that is for large samples). However a correction factor can be used to make results from small samples more accurate
The formular for Cohen's D is:
D = (mean1 - mean2) ÷ (√({standard deviation1}^2 + {standard deviation 2}^2)/2)
This is the most appropriate method in the given scenario

Step-by-step explanation:
For the points lol
I'm pretty sure it say "what percentage of £16 is 40p

Answer:
51/8 miles
Step-by-step explanation:
Given data
Jayson jogged 2 3/4miles on Monday
Let us expressed the number as a simple fraction
= 2 3/4
= 11/4 miles
on Tuesday
= 3 5/8
= 29/8
The total is
11/4+ 29/8
= 22+29/8
= 51/8 miles
Hence the total distance is 51/8 miles
