### SPSS output written up

Hi all members of SPSS forum

Apologies, for becoming a member to ask a question!

I am undertaking a research project regarding:

Is there an association between nutritional knowledge and protein intake of natural bodybuilders?

I have completed some results below: Do these results read and sound correct?

Data of male and female subjects that took part in the study are presented in Table 1. An independent-t-test revealed that male subjects ate significantly more calories (t=5.502, p<0.05). The data which was not significant a Mann-Whitney-U was conducted revealing significant differences between males and females for fat intake (U=0.0, p<0.05).

Table 1. Characteristics of male and female subjects (mean ± standard deviation).
Male (n=6) Female (n=6)
Height (m) 1.72 ± 0.08 1.64 ± 0.8
Weight (kg) 81.23 ± 12.17 61.17 ± 11.09
Age 31.50 ± 11.38 35.16 ± 11.72
BMI (kg/m2) 22.55 ± 4.53 24.45 ± 1.79
Calories (Kcal) 2787.67± 361.01 1817.50 ± 237.12*
Protein (g) 224.83 ± 68.62 154.17 ± 18.28
Carbohydrates (g) 294.33 ± 116.69 193.33 ± 47.29
Fat (g) 79.00 ± 35.21 47.50 ± 9.35*
Protein per gram of bodyweight (g) 2.73 ± 0.47 2.58 ± 0.45
NKQ Score 40.50 ± 3.78 41 ± 2.37
*Significantly different to males

Figure 1. Graph to show NKQ scores of each participant; x- axis arranged to display scores from highest on the left to lowest on the right.

There were 6 male and female participants. An independent-samples t-test was run to determine if there were differences in NKQ score between males and females. There were no outliers in the data, as assessed by inspection of a boxplot. NKQ scores for each gender were normally distributed, as assessed by Shapiro-Wilk's test (p > .05), and there was homogeneity of variances, as assessed by Levene's test for equality of variances (p = .403). Females had a higher mean NKQ score (M = 41.SD = 2.37) than males (M = 40.50, SD = 3.78), there was no significant difference, t=--0.275 p= >0.05

Figure 2. Graph to show NKQ scores and protein intake (g/kg/day) of each participant.

A Pearson's product-moment correlation was run to assess the relationship between NKQ score and protein intake (g/kg/day) within natural bodybuilders. Preliminary analyses showed the relationship to be linear with both variables normally distributed, as assessed by Shapiro-Wilk test (p > .05), and there were no outliers. There was a low positive correlation between NKQ score and protein intake, which was not statistically significant (r = .173, n = 12, p > .05).

My next question - Does anyone know how to do the below:

Thank you for your time and help

Take care

Dean

I don't understand what your question is.
