Overestimating enemy numbers, through faulty intelligence supplied to him by Allan Pinkerton.
McClellan was better at building an army(training,drilling etc.) than he was at field command(actually using the army in battle). He was often overestimating the numbers of Confederate troops opposing him and he regularly called for more troops to be sent to him when he already had superior numbers.
The 5 most suitable beaches in Normandy were selected and called Utah, Omaha, Gold,Sword and Juno. They were very carefully chosen for size, defences and type of sand/pebble. Most of it was excellent choice, except for drastically underestimating the protective German guns at Omaha.
His own natural caution, compounded by some vastly exaggerated estimates of enemy numbers, supplied to him by Pinkerton.
General McClellan was not effective as a military commander for several reasons. Firstly, he was known for his overly cautious approach, frequently overestimating enemy troop strength and being overly concerned about casualties. This led to unnecessary delays and missed opportunities. Additionally, he struggled with making decisive decisions and failed to fully utilize the resources and manpower at his disposal. Lastly, his strained relationship with President Lincoln and inability to effectively coordinate with other Union generals further hindered his effectiveness.
"Overestimating" means taking a guess at the value of a number but guessing too high. "Underestimating" means taking a guess at the value of a number but guessing too low.

the answer is overestimating and underestimating. An example is you could overestimate the money needed when going to the food store to shop for s party. An example for underestimating would be you could underestimate the number of guest that will attend the party. So you won't have a lot of left over food. If 100 people are invited most likely several people will not show up. I think over estimating is more useful, you never want to be caught without enough of anything. Extra is always best.
Underestimating the enemy.
Anchoring bias is a cognitive bias where individuals rely heavily on the first piece of information encountered (the "anchor") when making decisions. This can lead to underestimating or overestimating subsequent information, resulting in poor decision-making.
These things lead to us overestimating our intuition.

It means that you are ignorant of its true value
to calculate the standard deviation you must put each number in order from the least to the gr east then you must find your mean after you find your mean you must subtract your mean from each of the data set numbers once you finishsubtracting the data set numbers you add them up and divide by the amount of numbers there are and you have found the standard deviation.
