How to calculate spanner size regarding bolts and nuts
Yes.

Count up the number of obseravtions made on the experimental units. That is the sample size.
You cannot "calculate" the front of a box. You can calculate its dmensions, or its area but calculating it does not make sense. As for calculating its size or area, the answer will depend on what information you have and what you require.

Faster river velocities are capable of carrying greater amounts of bedload and transporting them farther and faster. The shape of the sediments of the bedload would therefore be exposed to more physical weathering which would progressively round the sediments and also decrease their size.
waste transported from the river!
Well, honey, as you travel downstream, the bedload size decreases because the heavier, larger particles settle out first closer to the source. And as for the roundness increase, well, that's just nature's way of giving those rocks a nice little spa treatment as they bump and grind their way downstream, getting smoother and rounder with each mile. So, in a nutshell, it's all about physics and erosion doing their thang as the river does its own version of a rock makeover.
To find river bedload, you can collect sediment samples from the river bed and analyze them in a laboratory. Another method is to use a sediment trap or gauge to measure the amount of sediment transported by the river over time. This can help determine the size and composition of the bedload in the river.
a bedload
bedload
Angular bedload consists of coarse sediment particles, such as gravel and cobbles, that are transported along a riverbed by rolling or sliding. These particles have angular shapes due to their solid and hard composition, which makes them more resistant to abrasion compared to more rounded particles. Angular bedload contributes to the erosion and sediment transport processes in rivers.
River efficiency is how easily a river can move water, sediment and bedload.

M. A. Carson has written: 'Bedload transport in gravel channels'
The size of the pebble will decrease down stream because the further downstream you go the quicker the river velocity. This means there will be more abrasion against the sides and bed of the river and the friction will be greater, this wears away the river load making it decrease in size. Increase velocity means that bigger material will be picked up by the river and carried as river load. More load in the river and increased size of load will mean more attrition and the river load will keep colliding into each other smoothening and rounding their shape. Brap brap !!
