jamovi

Hello,

I am writing my dissertation and running into a few issues. Mainly that my stats are not calculating, I have two missing values that participants did not answer the question on and then I am calculating this at the end so I can run analysis. However, my issue is that these values are blank and I can not give them a missing value of 0 as that is my measurement for deception and the absence of a number there is important. When I leave it blank it does not put anything in the total calculation and if I enter ignore_missing=1 then they report back as 0 when they should be much higher.

I have attached an image of it, the circle red is what I am being given with the calculation while the blue is what it should have (manually entered). I can not just use the manually entered values due to the fact that things such as the mean calculation will not take into account that they divide by 9 instead of 10 due to the missing answer.

If anyone knows the answer to this it would be much appreciated,
Thank you

For me, ignore_missing works a intended. See the image below or attached.

If it's of any use I have attached my datasheet, this is a really frustrating issue I can't find the answer to

hi,

jamovi is actually doing the right thing here. you're adding all the values together, and *then* taking their sum. rather than:

SUM(Q6_1C + Q7_1C + Q8_1C + Q9_1C + Q10_1C + Q11_1C + Q12_1C + Q13_1C + Q14_1C + Q15_1C, ignore_missing=1)

use this instead:

SUM(Q6_1C, Q7_1C, Q8_1C, Q9_1C, Q10_1C, Q11_1C, Q12_1C, Q13_1C, Q14_1C, Q15_1C, ignore_missing=1)

cheers

You are an absolutely lifesaver

Can I ask will this automatically be considered in the calculations, for example with the descriptives will it automatically consider this when calculating the mean that it should divide by 9 instead of 10. My total is being turned into a percentage at the end (5.4 mean, becoming 54% accuracy) so its quite important that this is accurate. Thank you again

Descriptives works properly. See below/attached.
