Question

Does anyone know how to predict prices of products in the future? I have a maths assessment and it is about percentage. I have to calculate the percentage of the given products and write a report about the prediction of prices of those products in the future. Can you guys please help me?

Answer 1

I don't know how to do that but my teacher told me that we have to add all of the calculated percentage and divide by 2; the result is the prediction. I don't understand what she said. Do u know how to do that?

Answer 2

Can you post it, so I can figure out the concept?

Answer 3

alright

Answer 4

I hv all of the calculation but i just dunno how to predict the prices

Answer 5

Because in the table, the increase and decrease prices already calculated each year.
-> There's not much to do, except find the average by get sum, ( negative and positive value ), then divide by 2.

Answer 6

Briefly, the idea is use average as estimation for the price!

Answer 7

i got it thx :)
but how to find the decrease/increase in each years? i hv to find the prices for the next 3yrs i.e. 2012-2013, 2013-2014, and 2014-2015. Is it to divide the half average that is found by 3?

Answer 8

The last column is % -> calculate on the last column only :)

Answer 9

oh...

Answer 10

Just careful when you see decrease, for example:
Increase 20 %, decrease 14.10% = 20 - 14.10 = ...%

Answer 11

this is like a moving average im guessing

Answer 12

@dumbcow so m i correct doing like this?

Answer 13

sorry, im not sure exactly what you are supposed to do
i was just guessing...predicting/forecasting is tricky work because mainly its just educated guesses based on previous observation
