The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. For example, if A is the set {♢,♡,♣,♠}, then ♡∈A but △∉A (where the symbol ∉ means “not an element of”).
ε: “Error term” in regression/statistics, more generally used to denote an arbitrarily small, ∈ (Variant Epsilon) This version of epsilon is used in set theory to mean “belongs to” or “is in the set of”: x ∈ X, similarly used to indicate the range of a parameter: x ∈ [0, 1].
That is a capital Sigma (from the Greek alphabet). It stands for "Sum".
Expected ValueIn a probability distribution , the weighted average of possible values of a random variable, with weights given by their respective theoretical probabilities, is known as the expected value , usually represented by E(x) .

The greek letter epsilon, written ϵ or ε, is just another variable, like x, n or T. Conventionally it's used to denote a small quantity, like an error, or perhaps a term which will be taken to zero in some limit.
E = (zc * s)/sqrt(n) Note that “s” is the sample standard deviation.
In a probability distribution , the weighted average of possible values of a random variable, with weights given by their respective theoretical probabilities, is known as the expected value , usually represented by E(x) .
Omega (uppercase Ω, lowercase ω) is the 24th and last letter of the Greek alphabet. In the Greek numeric system, it has a value of 800.
Vacuum permittivity, commonly denoted ε0 (pronounced as "epsilon nought" or "epsilon zero") is the value of the absolute dielectric permittivity of classical vacuum. Alternatively may be referred to as the permittivity of free space, the electric constant, or the distributed capacitance of the vacuum.
e is the desired level of precision (i.e. the margin of error), p is the (estimated) proportion of the population which has the attribute in question, q is 1 – p.
In general, a range of 1 to 3 sets of an exercise can provide benefits based on your goals, and even just one exercise per muscle group can give you results. To gain strength, it's best to stick with a few foundational exercises and concentrate your reps and sets there.
Then compare each paper to one half. 1 3 < 3 4 One third is less than one half, and three fourths is greater than one half.
