Показатель результативности вырос, то есть стал выше.

Because Russian often expresses X of Y with a noun + genitive pattern.

Here:

• показатель = indicator, measure
• результативности = of effectiveness / of performance

So показатель результативности literally means indicator of performance/effectiveness.

This is a very common structure in Russian, for example:

• центр города = city center, literally center of the city
• уровень жизни = standard of living, literally level of life

It is a noun phrase meaning something like:

• performance indicator
• effectiveness indicator
• performance metric

The exact English translation depends on context.

Word by word:

• показатель = indicator, index, metric, measure
• результативность = effectiveness in producing results, performance

So this is the thing that increased: the metric itself.

Вырос is the past tense of the perfective verb вырасти.

Compare:

• расти = to grow, to be growing, to grow over time (imperfective)
• вырасти = to grow/increase to a new point, to end up higher (perfective)

In this sentence, the speaker is talking about a completed change: the indicator went up. That is why perfective вырос is used.

Very roughly:

• показатель рос = the indicator was growing / used to grow
• показатель вырос = the indicator increased / has gone up

In the past tense, Russian verbs agree with the subject in gender and number.

The subject here is показатель, which is masculine singular, so the verbs are also masculine singular:

• показатель вырос
• показатель стал выше

Compare:

• цена выросла = the price increased
  because цена is feminine
• показатели выросли = the indicators increased
  because показатели is plural

То есть means that is, i.e., or in other words.

It introduces a clarification or restatement.

So:

• Показатель результативности вырос = The performance indicator increased
• то есть стал выше = that is, it became higher

The second part explains the first in simpler terms.

Yes, they are very close in meaning here. The second part is an explanation or paraphrase.

This is common in Russian, especially in formal, explanatory, or teaching-style language:

• first, a more compact verb: вырос
• then, a clearer rewording: стал выше

So the sentence is essentially saying:

• the indicator increased,
• in other words, it became higher

It is not adding a new event; it is restating the same idea.

This is a very common Russian pattern:

стать + comparative = to become more ...

Here:

• стал = became
• выше = higher

So стал выше literally means became higher.

Other examples:

• стал лучше = became better
• стала понятнее = became clearer
• стало труднее = became more difficult

Because Russian often describes levels, indicators, prices, and rates as higher/lower, not just bigger/smaller.

So with things like metrics, percentages, and levels, выше / ниже is often very natural:

• уровень стал выше = the level became higher
• показатель стал выше = the indicator became higher

Больше usually means more or larger in quantity/amount. It can sometimes work in related contexts, but выше is more idiomatic here because the idea is about level.

Yes, very often you can.

• Показатель вырос
• Показатель повысился

Both can mean the indicator increased.

The difference is mostly stylistic:

• вырос is very common and broad
• повысился can sound a bit more formal, technical, or administrative

In many contexts, either one would be fine.

Because то есть introduces an explanatory restatement.

Russian normally puts a comma before то есть when it means that is / in other words:

• Он опоздал, то есть пришёл позже всех.
• Показатель вырос, то есть стал выше.

So the comma marks the start of the explanation.

Yes. Показатель результативности вырос is a neutral, standard word order:

• subject first
• verb after

Russian word order is flexible, though. You could also say:

• Вырос показатель результативности.

That version puts more emphasis on the fact of increase itself. But the original sentence is the most neutral and textbook-like.

Because Russian does not have articles like the or a/an.

So показатель can mean:

• the indicator
• an indicator

The context tells you which one is meant. In this sentence, English naturally uses the because it sounds like a specific indicator already known from context.

They are close, but not always identical.

• результативность focuses on getting results, achieving an outcome
• эффективность can mean effectiveness, but often also has a sense of efficiency

In many practical contexts, they may both be translated as effectiveness or performance, but the nuance of результативность is more specifically about how successful something is in producing results.
