Question

Conduct a two-way chi-square analysis in SPSS to examine whether or not there is a relationship between the location of thefts and the value of property stolen

I have attached the 2 way Chi Square analysis below

Chi-Square Tests Asymptotic Significance (2-sided) Value df Pearson Chi-Square 44.279a Likelihood Ratio N of Valid Cases 34 112 44.345 74 34 50 cells (92.6%) have expected countless than 5, The minimum expected count is .22 Symmetric Measures Approximate Significance 112 112 Value 774 547 Nominal by Nominal Phi Cramer's V N of Valid Cases

Explanation / Answer

Answer to the question#1)

Statistical significance is possible when the P value < 0.05

Since we got P value 0.128 > 0.05 , the results are statistically insignificant , and therefore practically also insignficant

Thus the correct answer ic "niether statistically significant nor practically significant"

.

Answer to the question#2)

The effect size is provided by the phi value in the second table

We got phi value = 0.774 ~ 0.77

Thus the effect size is 0.77

.

Answer to the question# 3)

The computed chi square value can be obtained from table 1 of the output

Pearson chi square = 44.279

.

The chi square critcal value is:

df = 34 , significance level = 0.05

Enter the formula in excel

=CHISQ.INV.RT(0.05,34)

we get chi critical value = 48.6024

Thus chi statistic is less than chi critical value

.

Answer to question# 4)

The probability value = 0.112

In percent it becomes = 0.112 *100 = 11.2%
