Question

Research Questions: For female patients of a medical practice, was there a difference in mean scores of satisfaction with their doctor and satisfaction with their life? For male patients of a medical practice, was there a difference in mean scores of satisfaction with their doctor and satisfaction with their life?

Anyone knows how to get the minitab output of this question??

Answer 1

do you already have the file? and the program to run minitab stuff?

Answer 2

yup

Answer 3

i have data and i want to know how to draw it from minitab

Answer 4

i need help to get minitab output from these data

Answer 5

have you used the mini tab before?

Answer 6

yup

Answer 7

I'm learning now

Answer 8

ive never used it so the best i could do is follow a manual.

we want to define some variables and have it compute a line of best fit right?

Answer 9

or some statistical output that tells us about the data

Answer 10

nope , it's not finding the best fit

Answer 11

ok, then tell me what your thoughts are

Answer 12

its box plot and histogram

Answer 13

pg 55 thru 57

Answer 14

For example, select score of satisfaction with their life for samples and sex for subscripts

Answer 15

this seems like the old version

Answer 16

old versions and new versions differ very little in most programs. what version do you have?

Answer 17

minitab 17

Answer 18

i think is the latest version

Answer 19

anyway, thx for your help

Answer 20

http://www.minitab.com/uploadedFiles/Documents/getting-started/Minitab17_GettingStarted-en.pdf

but you probably already have a manual right

Answer 21

i dont have the program so i just cant dabble with it to see what i can do ....

Answer 22

i can down the trial version

Answer 23

nvm, i got the software from my uni

Answer 24

Normally, we have one subscript and one sample to draw a box plot but this question has two samples and one subscript

Answer 25

Any minitab expert??

Answer 26

im still gonna play with it, got a 30 day free trial lol

Answer 27

quick question .... how do we get it to read the patients file?

Answer 28

got it, it was called a worksheet ...

Answer 29

ya open the file with minitab

Answer 30

sex, 1 male 2 female?

Answer 31

yup

Answer 32

do you know hypothesis test?

Answer 33

i need to construct a hypothesis test to answer the research question

Answer 34

well ive managed to get 2 histograms to pop up, sex=1 and sex=2 based on column 2 frequencies.

Answer 35

i can do some basic hypot tests yes

Answer 36

sorry but that looks weird

Answer 37

i think the shape should looks like approximately normal

Answer 38

appreciate a lot

Answer 39

hmm, the stem leaf outline for sex=1, suggests a 2 peak historgram as well.

2 678999

3 123334466777899 <--- peak 1

4 01224557

5 1233444556778899

6 0000001111233345556677888999 <-- peak 2

7 0014

8 011129

9 13

Answer 40

what do you want to use for intervals?

Answer 41

95

Answer 42

95 confidence interval

Answer 43

i was talking about histogram class intervals :) not hypot test at the moment

Answer 44

I didn't learn about this O.O

Answer 45

but the shape is too skewed

Answer 46

the shape is bimodal, its what the data gives us

Answer 47

actually, i have to draw the output according to the type of the hypothesis test

Answer 48

and this is a two sample t-test

Answer 49

there are 8 different hypothesis tests

Answer 50

From the minitab, press Stat> basic statistics> 2 sample t-test

Answer 51

like that?

Answer 52

yup

Answer 53

but there are two samples which are the score of satisfaction with their life and doctor

Answer 54

and sex is the subscript

Answer 55

are we comparing the means of satlife_male with satdr_male?

because i just did satdr_male with satdr_female ....

Answer 56

mean of satlife and satdr between male and female

Answer 57

thats confused

Answer 58

let me see if i understand that:

combine satdr_male with satlife_male as 1 sample

and the other sample is the combination of the female stuff

Answer 59

I think like that as well , if thats the case i need to draw many histogram and box plot

Answer 60

histogram is use to do the assumption for normality

Answer 61

box plot use to determine the spread

Answer 62

i recall something about

mean(a+b) = mean(a) + mean(b)

and variances of a combined sample add as well.

Answer 63

if the sets are independant

Answer 64

so sats life and sat dr are independent?? do you think

Answer 65

So do i need to draw like box plot of satdr for male and female and sat life for male and female

Answer 66

i think they are, but om not an expert

Answer 67

okay i think i will ask my tutor :) thx for helping

Answer 68

good luck, my eyes are getting heavy :)

Answer 69

:)
