K-Means Cluster Analysis in SPSS

This video demonstrates how to conduct a K-Means Cluster Analysis in SPSS. A K-Means Cluster Analysis allows the division of items into clusters based on specified variables.

I wish I had never studied data science. This is painfully boring. But I Love you Todd youre saving my life frfr

[majkalapkova]

Thank you man, you're still saving lives out here!

This example was outstanding. I have DV three subscales that I have standardized: Self Esteem, Leadership Efficacy, and Leadership Activism. I have one Categorical IV: Type of mentoring Program: A) One-on-One, B) Team Mentoring, C) Online mentoring, D)Group Mentoring. I'm interested in knowing where these scores (low-high) fall under each Mentoring Type. Ran the analysis. How do I link the cluster to the mentoring type? In the first analysis I used a default cluster, Second analysis, I created 4 groups, which were significant. Should I then create a crosstab of Mentor Type by Group?

I'd never thought I'd found a video about kmeans from Dr. Grande, wow.

Hi, can you interpret what these clusters mean for the example ID's? so for example the second cluster of patients have very high dep and sub. use, but score low in anxiety? is this correct? thanks Dr. Todd

[aination]

So now, which one do we choose as the value of k?
2 or 3?

Hi, I was wondering how to read in cluster centers from an external file (after having done the hierarchical clustering) as SPSS always shows error messages (not correct format or one variable name is incorrect). Do you have a video for that? or any solution to my problem?

[mehmettolgataner]

Dear Dr. Grande. I downloaded SPSS29 but am not able to perform this. The 29th version is totally differe nt.

[chrisparker]

So what is it, two clusters or three clusters?

[tacs]

can u explain the need to standardise the variables in this case? 
it seems they are more or less within the same range, so why the need to standardise?

[martinl]

Thanks for the video. I have two questions:

1- Why did you perform a standardize method at a very early stage?

2- Is the standardize method recommended always or only for some cases?

[lealyniligan]

Hello can I get the copy of raw data u used for this tutorial?

[wvrkcqs]

Can i proceed to K-means cluster analysis without standarizing the variables?

[musabara]

This is a very good video, please Dr do also have SOM clustering analysis in SPSS?

[edonuzi]

Thanks for the video! please, how do I combine k-means with mlp in an ensemble form using ibm spss? Also how do I find the ideal cluster number for k means?

[zeeb]

i never know if this 5 years ago video will helping me now

[MalayKumar]

Someone please tell me why do we use K-Means?

[tmitra]

Man, you have to do something with your audio, Don't you listen to your video before uploading??
