Since the test results are displayed in B2-B10 youll need to make sure that data is used in your formula. Again first of all we will find the impedance Z of the circuit. The number of classes can be estimated using the rounded output of Sturges rule N 13322logn N 1 3322 log n where N N is the number of classes and n n is the number of items in the data set.
F 1 T.
The formula for determining the frequency during this event is as follows. In this case your formula is telling Excel to look at B2-B10 and use the ranges in C2-C4 to calculate frequency. Sound travels in waves and does so at a particular speed depending on what it is travelling through such as air brick or water. Where o is the angular frequency.
