ployee inputs, “through a series of different screens, a set of created part numbers, along with other information about the product and parts to garage doors into the COPICS system which creates the bill of materials.” Information is similarly entered into the Friedman system which creates the parts master file. The information contained in these two systems allows the Frantz Division to keep track of what parts are used at the different stages of the manufacturing process, as well as the cost of those parts. This information is pulled up on computers to enable the production schedulers to determine customer needs and parts availability for specific products.
Once Fisher was told that his position had been eliminated as part' of the RIF he was given the opportunity to bump a less senior employee from a list of nine different jobs. He took advantage of this opportunity and moved into a laborer position. Due to subsequent physical limitations, Fisher went on disability and later returned to other positions at Frantz Division. On December 15, 1995, he filed a complaint against defendants in the district court alleging that he was discriminated against in violation of the ADEA when Matznick was given the remaining position in the Production Control Department rather than him. At the time of the RIF Matznick was 39 and Fisher was 63. Fisher was laid off on January 19, 1996. The district court granted summary judgment because Fisher could not establish a prima facie case of age discrimination or, even if he could, he was unable to show that the legitimate non-diseriminatory reason given for his discharge was pretextual.

This court reviews a district court’s grant of summary judgment de novo. Venters v. City of Delphi, 123 F.3d 956, 962 (7th Cir.1997); Oates v. Discovery Zone, 116 F.3d 1161, 1165 (7th Cir.1997). “Summary judgment is appropriate when the record, viewed in a light most favorable to the non-moving party, reveals that there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law.” Vector-Spring field Properties, Ltd. v. Central Ill. Light Co., Inc., 108 F.3d 806, 809 (7th Cir.1997) (citing Fed.R.Civ.P. 56(c)). In order for a party “to avoid summary judgment that party must supply evidence sufficient to allow a jury to render a verdict in his favor.” Williams v. Ramos, 71 F.3d 1246, 1248 (7th Cir.1995). In an employment discrimination case, a claimant must present more than conclusory allegations to defeat a motion for summary judgment. Mills v. First Federal Sav. & Loan Ass’n of Belvidere, 83 F.3d 833, 840 (7th Cir.1996). The mere existence of some alleged factual dispute is insufficient to defeat an otherwise properly supported motion for summary judgment. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247-48, 106 S.Ct. 2505, 2509-10, 91 L.Ed.2d 202 (1986).
“A plaintiff can avert summary judgment for the defendant in an employment discrimination case either by putting in enough evidence, whether direct or circumstantial, of discriminatory motivation to create a triable issue or by establishing a prima facie case under the McDonnell Douglas formula.” Sheehan v. Daily Racing Form, Inc., 104 F.3d 940, 940 (7th Cir.) (citing McDonnell Dovelas Corp. v. Green, 411 U.S. 792, 93 S.Ct. 1817, 36 L.Ed.2d 668 (1973)), cert. denied, — U.S. -, 117 S.Ct. 2480, 138 L.Ed.2d 989 (1997). Fisher attempts both methods to avoid summary judgment.

Fisher claims to have direct evidence of age discrimination. Although after the RIF there remained a slightly increased percentage of workers over 40, Fisher nevertheless argues that defendants discriminated based on age among those who were between the ages of 40 and 70. Fisher asserts that the defendants targeted workers over 60 for termination during the RIF, because five out of the six oldest office workers lost their jobs. This argument is unavailing because, aside from this being a small sample size, Fisher does not provide necessary facts pertaining to qualifications for the jobs remaining. Nor does he even attempt to rule out any “potential explanatory variables” such as the inverse relationship between age and computer familiarity. Sheehan, 104 F.3d at
