11.1 Random and systematic errors (SL)

Understandings:
Experimental design and procedure usually lead to systematic errors in measurement, which cause a deviation in a particular direction.
Repeat trials and measurements will reduce random errors but not systematic errors.
Applications and skills:
Distinction between random errors and systematic errors.
Discussion of systematic errors in all experimental work, their impact on the results and how they can be reduced.

overshooting the endpoint in a titration (systematic) and not properly reading the units (random) are both mistakes that the student can make in the experiment and is therefore random, I suppose. Why isn't shooting the endpoint in the titration a random error in that sense - especially if the procedure of an experiment does not instruct one to do so.

Hello Sir.
I appreciate your videos because they look organized.
If someone did not draw a calibration curve, can it be a systematic error?

What are formulas for calculating both?

my dad let me saw all your video because of this video😤😤😬😡

0.36: why is insufficient data random error when its a flaw in the experiment in that the person does not conduct enough trials?
Thanks

1:20 The absolute uncertainty of the 50mL beaker seems really high. I think you might have forgotten the the decimal there - I might be wrong as well.

Thank you sir

both kinds of errors contain apparatus. For weighing the NaOH, it systematic or random error?

[saeedelghaziri]

So reading something constantly wrong is both random and systematic right?

I am getting depressed with my grades every week in chemistry, we are always overloaded with tasks and information and I can't follow it anymore. I keep failing that I lost the excitement I had during studying.

isnt "overshooting the endpoint in a titration" a random error as it's the person's fault and it decreases in each experiment; and it can be likely to be any of a bit more or bit less than the actual value.
