Prepare time series data

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

The same task, four prompts

Load the 'stock_prices.csv' data, which has 'Date' and 'Close' columns, and create a time series object from it, resampling to weekly averages.

Before I send this power consumption data to the facilities team, prepare the time series: fill any missing hourly values using linear interpolation, smooth out the noise with a 24-hour moving average, and resample it to daily totals, so they can see clear trends.

I'm trying to plot the 'Sensor_1_Data' time series against 'Sensor_2_Data', but they have different timestamps and lengths.
I'm trying to plot the 'Sensor_1_Data' time series against 'Sensor_2_Data' for the anomaly detection report, but they have different timestamps and lengths, so I can't compare them directly. The project lead needs to see this comparison by Friday afternoon, and I'm afraid I'll miss the deadline if I can't align them. I can't tell if the sampling rates were different or if there's a clock drift. What's the most likely issue, and what's the best way to synchronize these two time series for a proper comparison?

I frequently waste time manually aligning time series data from different sources with misaligned timestamps.
I frequently waste time manually aligning time series data from different sources with misaligned timestamps or missing values before I can perform comparative analysis. This happens every time we integrate new experimental setups. What habit should I change in my initial data preparation routine to automatically handle these misalignments and make the data ready for comparison more efficiently?

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from MATLAB's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
