Perform data analysis

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.

Load the 'experimental_results_batch_3.mat' file. Calculate the mean and standard deviation for the 'sensor_readings' variable. Plot a histogram of these readings with 20 bins, labeling the axes as 'Sensor Value' and 'Frequency'. Save the plot as 'batch3_sensor_histogram.pdf'.

Before I present this data analysis to the funding committee, make it more persuasive. Identify any outliers in the 'experimental_data' and suggest a robust method to handle them. Also, perform a statistical test to show the significance of the observed difference between 'control_group' and 'treatment_group' and present the p-value clearly.

The new batch of experimental data from the lab is showing unexpected spikes and drops that don't align with previous runs.
The latest batch of experimental data, due for preliminary review by Dr. Chen tomorrow, has unusual spikes and dips that weren't present in prior runs. I'm afraid to present it as-is, but I also can't just discard it without understanding why. It could be a sensor glitch, a new environmental factor, or even a real, but unexpected, phenomenon. What's the best diagnostic approach to quickly identify the source of these anomalies without prematurely drawing conclusions?

DBecome — change the patternI often find that when I go back to old projects or share my data analysis with a colleague,…+
I frequently struggle to reproduce my analysis results exactly when I revisit older projects or share them with colleagues.
I often find that when I go back to old projects or share my data analysis with a colleague, reproducing the exact results is difficult due to missing steps or forgotten configurations. This undermines confidence and wastes time. What habit should I change to ensure my data analysis workflows are consistently reproducible and transparent, making it easier to pick up where I left off or for others to verify my work?

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.
