Lifespan study / Killing assay - Statistic Analysis

I am looking for some assistance in statistic analysis by using computer software. Is there any recommendation of software that researchers to use ? i’ve heard of StatView and Graph Pad Prism.

any input will be most welcomed.

Graph pad prism is awesum
I generally do all my statistical analysis using that.

Hello

Graphdpad prism is probably the simplest way to go. It has some templates built-in. However, it does not calculate mortality rates (I think :))

Also, in case access to Graphpad is not possible, you can format the data for use in SPSS (which also has a macro to calculate Log-rank tests)
