Hi All! I want to calculate the mode of 20 values my echo-sensor has given me. However, I have no idea how to calculate this. Do I actually have to download a certain library for this, or is there a little coding trick I can do to calculate it? The looping code is pasted here, if that helps.

if (start == true) {
for (i = 0; i < 20; i++) {
digitalWrite(trigEcho, LOW);
delay(2);
digitalWrite(trigEcho, HIGH);
delay(10);
digitalWrite(trigEcho, LOW);
time = pulseIn(Echo, HIGH);
distance= time*0.0343/2;
Serial.println(distance);
}

Thank you guys for your help! I made a mistake in the forum post though.. What I need to calculate is actually the mode instead of the median. I always mix those up haha...

I think calculating the mode is way too difficult compared to the level that I am at rn though. Someone else has asked this once and I would have to use an array of 8-bit unsigned integers. I have no clue what this means so I'll probably just filter out outliers by hand another way.
