On the discriminantquestion why don’t you not use the 3 in 3-c
@mrraynermaths4118
@mrraynermaths4118 Жыл бұрын
Hi, the 3 has been used, but for space and likely time saving, I completed the steps in one. The breakdown would be: 16 -8(c-3) = 0 16 - 24 + 8c = 0 -8+8c = 0 c = 1

In case you need this: type_A_uncertainty = st_dev(X) / sqrt(n) Being n the number of samples.

is there a way to see the Quartiles, percentiles & Deciles in this calculator ?
@mrraynermaths4118
@mrraynermaths4118 Жыл бұрын
Hi - there is a way to see the quartiles, but not the percentiles and deciles. Once you have entered your frequency table, you want to press "shift" and "1" to enter the statistics calculation mode. On this mode, you want the minmax function to get the 5 number summary. This will be the min, max, Q1, 2 and Q3 of the data input.

I think that seven randomly selected students is a sample (the size of the sample is smaller than populations). The population would be all the students who took the test. So, i got a little confused when you said tha "sx" is a sample population. What does that mean? And if you meant sx is the standard deviation of the sample, then shouldnt we use this instead of σx ?
@mrraynermaths4118
@mrraynermaths4118 2 жыл бұрын
Hi, you would use sx for a sample from the overall population and σx to find the actual standard deviation given the data for the entire population. Effectively, sx is an estimate for the s.d when we only have a sample.
