Are the data quadratic?
Yes No
Homework Answers
Given Data Table
To FIND First Order Difference you subtract consecutive y values
For example in this data table find
y2 - y1
y3 - y2
y4 - y3
y5 - y4
IF all these values are same than it can be said data is linear IF not then find Second Order Differnece
CLearly data is not same
So we find Second order Differnece
Let previous values be x1, x2, x3, x4
To find we find consecutive difference again
Since all the values are same we can say that data is quadratic
So In one table data looks something like this
Please comment for any further assitance

Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis H_0: mu_D = 0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a treatment. Assume the population of the differences in these measurements are normally distributed. Complete the following table by calculating the differences and the...
