How do I simulate packet drop while sending packets from Linux Box

Question

I wanted to simulate a situation where when I send some packets say ping x.x.x.x, some of my packets outgoing from my Linux box should be dropped out and number of dropped packets should be then captured through Tx dropped packets in ifconfig tool.

I know some of option/rule that we can provide in iptables but not sure about them.
